[Energy loss by the body during gastrectomy].

A method for calculation of the loss of energy by an organism of a patient at the time of gastric resection is presented. It is shown that for the 2h of operation, a patient losses the amount of energy which is almost equal to the basal metabolism for 24 hours.

An attempt at real prophylaxis of primary dysmenorrhea: comparison between meclofenamate sodium and naproxen sodium.

Dysmenorrhea is a widespread phenomenon, affecting mainly young nulliparous women, often inducing difficulties in study or in work. Its pathogenesis involves a release of local vasoconstrictors like Prostaglandins and Leukotrienes. Modern therapy is based firstly on the administration of prostaglandin-Synthetase Inhibitors or Contraceptive Pills, with the aim of reducing the menstrual excess of pain inducing substances. In order to achieve more efficacy, on the basis of the already proven effectiveness of the Non Steroid Anti-Inflammatory Drugs (NSAID)s in this field, we recently set out to prevent dysmenorrhea in a double-blind randomized study with Meclofenamate Sorium and Naproxen Sodium. Through the observation of the drop in Basal Body Temperature which usually precedes menstrual flow, we were able to instruct our patients in the earlier recognition of impending menstrual onset, leading to earlier prevention of Prostaglandin and Leukotriene release. Meclofenamate Sodium in particular led to considerable pain reduction, with very good patient compliance and without significant complications, probably of its additional receptor effect.

A statistical approach to the determination of the fertile period.

17 beta-Estradiol (E2), basal body temperature (BBT) and luteinizing hormone (LH), were measured in normally menstruating women. The preovulatory E2 observations were characterized by variations about a constant level during the preovula-peak. The BBT observations typically varied about a constant level during the preovulatory phase then about a higher constant level during the postovulatory phase. The change points in E2 and BBT were detected using a Bayesian detection rule and a midcycle 'fertile period' was marked off. The midcycle 'fertile periods' appear to bracket the ovulation event and the method shows promise as a natural family planning method. Several practical limitations of the method are discussed.

Anomalies of autogamy in Paramecium tetraurelia temperature sensitive mutant induced by heat treatment.

The run of autogamy in temperature sensitive mutant ts401, carrying also the mutation of trichocysts nd3a, at permissive (26 degrees C) and non-permissive temperature (35 degrees C) was studied and compared with this process in wild d4-2 stock of Paramecium tetraurelia. The effect of heat treatment on programmed nuclear and cortical events was investigated using cytological silver impregnation Fernandez-Galiano method and immunofluorescence technique with the application of two anti-alpha-tubulin antibodies. The appearance of cells with some large macronuclear fragments and an excess number of micronuclei suggests that nuclear differentiation is inhibited at restrictive temperature and that macronuclear regeneration takes place in this thermosensitive mutant. In such cells impaired oral reorganization was observed. After slight refeeding at the late autogamy, cells stopped at first postautogamous division were induced by heat treatment. The most striking feature of these abnormal divisions was the lack of a basal body duplication wave, which suggests that production of gamma-tubulin, structural protein being the essential component of the microtubule organizing centres, is disturbed at high temperature.

Cyclic changes in salivary lactate dehydrogenase, peroxidase and leucine aminopeptidase during menstrual cycle.

Salivary lactate dehydrogenase (LDH), peroxidase (Px) and leucine aminopeptidase (LAP) activities were scanned in both normally ovulating and anovulating women during entire menstrual cycle. In ovulating women, all the three enzymes exhibited significant increase in the activity on or before the onset of ovulation which was monitored by the shift of the basal body temperature (BBT) as well as the ferning pattern of the cervical mucus. The peak maximum at the midcycle was several times higher than the previous day value in all the six normal women. In anovulatory women, no such remarkable change in the enzyme activities was found throughout the cycle. Salivary LDH and LAP showed peak at the midcycle and at the same time required short time for assay, so the present results are strongly suggestive that the determination of salivary enzyme content may be a convenient method for detecting the day of ovulation.

Basal body temperature assessment: is it useful to couples seeking pregnancy?

Advanced practice nurses in primary care settings are often asked to give appropriate advice to couples seeking pregnancy. This article examines the issue of basal body temperature (BBT), a time-honored way to establish the presence of ovulatory cycles, and asks if BBT is an outdated recommendation. The article also reviews the benefits and limitations of recommending BBT to couples seeking pregnancy in light of recent fecundity research.

Rewarming index of the lower leg assessed by infrared thermography in adolescents with type 1 diabetes mellitus.

The aim of this study was to determine whether infrared thermography before and after challenge of the lower leg in cold water may be a useful tool to detect abnormalities in skin blood flow in adolescent asymptomatic patients with type 1 diabetes mellitus (DM1) and to assess the optimal setting of skin temperature measurements. Twenty-five adolescents (10 female, 15 male, mean age 21.2 +/- 6.2 years, body mass index [BMI] 23.0 +/- 2.1 kg/m2) with a duration of DMI of 13.8 +/- 5.4 years and mean HbA1c levels 8.5 +/- 1.3% were compared to age- and sex-matched controls (BMI 22.9 +/- 2.2 kg/m2). Seven defined sites of the lower leg were assessed by infrared thermography before and for 10 min after exposure of the leg to 14 degrees C cold water. As skin temperature before exposure to cold water differs from individual to individual and basal temperature was significantly warmer in patients at the tip of the first (p < 0.05) and fifth (p < 0.05) toe, the rewarming index was calculated in order to compare data. Rewarming indexes of skin temperature during the whole measurement procedure (0-10 min) were significantly lower at the tip of the first (p < 0.05) and fifth (p < 0.01) toes and from minute 2-10 also at the inner ankle (p < 0.05) in patients compared to healthy controls. Rewarming indexes of the other four sites were not significantly different between patients and controls. Infrared thermography of the lower leg after cold water exposure is an easily applicable method and a useful tool to detect abnormalities of skin blood flow in adolescents with DM1 especially at the tips of the first and fifth toes and the inner ankle.

Acamprosate and alcohol: II. Effects on alcohol withdrawal in the rat.

The suppressing effect of acamprosate (calcium-acetyl homotaurinate) on alcohol drinking is well established; however, little is known about its effects upon the alcohol-induced withdrawal syndrome. Male Wistar rats received as a sole drinking fluid a 20% (v/v) alcohol solution for one week. Animals consumed on average 5.3 +/- 0.3 g/kg per day alcohol, which resulted in blood alcohol levels of 38 +/- 14 mg/dl. For the quantification of alcohol withdrawal we used a new radio-telemetric system which enabled us to monitor body temperature, locomotor activity, food and water intake patterns constantly during alcohol withdrawal. Although alcohol intake and the resulting blood alcohol levels were low, clear signs of withdrawal could be observed. Thus, hyperthermia and hyperlocomotion occurred 18 h after the termination of forced alcohol drinking. Food intake was initially enhanced but dropped significantly below basal food intake in control animals one day after the termination of forced alcohol drinking. Acamprosate given twice a day (200 mg/kg, i.p., 8 a.m. and 8 p.m.) reduced hyperlocomotion and food intake significantly in the alcohol withdrawal animals, however, it did not change withdrawal-induced hyperthermia. When acamprosate was given to alcohol-naive animals, it increased locomotor activity and body temperature transiently, in particular during the rats' active night phase. In summary, (i) the radio-telemetric system used in the present study proved to be a very sensitive method for quantifying alcohol-induced withdrawal symptoms; (ii) acamprosate reduced alcohol-induced physical signs of withdrawal, however, this effect could not be observed for all parameters measured, which might be explained by the fact that (iii) acamprosate exerts a slight, transient psychomotor stimulant effects by itself.

Day-specific probabilities of clinical pregnancy based on two studies with imperfect measures of ovulation.

Two studies have related the timing of sexual intercourse (relative to ovulation) to day-specific fecundability. The first was a study of Catholic couples practising natural family planning in London in the 1950s and 1960s and the second was of North Carolina couples attempting to become pregnant in the early 1980s. The former identified ovulation based on the ovulatory shift in the basal body temperature, while the latter used urinary assays of hormones. We use a statistical model to correct for error in identifying ovulation and to re-estimate the length of the fertile window and day-specific fecundabilities. We estimate the same 6-day fertile interval in both studies after controlling for error. After adjusting for error both data sets showed the highest estimate of the probability of pregnancy on the day prior to ovulation and both fell close to zero after ovulation. Given that the fertile interval is before ovulation, methods that anticipate ovulation by several days (such as the assessment of cervical mucus) would be particularly useful for couples who want to time their intercourse either to avoid or facilitate conception.

Energy expenditure in men and women during 54 h of exercise and caloric deprivation.

UNLABELLED: Fifty U.S. Marine recruits (30 men, 20 women) were studied during a physically intense, energy intake-restricted, winter-time 54-h field training exercise (FEX) at Parris Island Marine Corps Recruit Depot. Men and women completed the same physical tasks. PURPOSE: To characterize and compare the total energy expenditure (TEE) and core temperature responses in men and women working almost continuously for 2.25 d in an outdoor environment while developing a substantial energy deficit. METHODS: TEE was measured using doubly labeled water (D(2)O(18)). Energy intake was estimated using beverage diaries and collecting ration wrappers saved by each volunteer and adding the known caloric value of each food item consumed. Core temperature was measured using an ingested thermometer pill. Physical activity level (PAL) was calculated by dividing TEE by the calculated basal metabolic rate. RESULTS: TEE was higher (P < 0.001) for the men (25.7 MJ.d(-1)) than women (19.8 MJ.d(-1)), but there were no differences between men and women in TEE normalized to body mass (men, 0.35 +/- 0.05 MJ.d(-1).kg(-1); women, 0.34 +/- 0.06 MJ.d(-).kg(-1)), corrected body mass (men, 0.29 +/- 0.04 MJ.d(-1).kg(-1) corrected body mass; women, 0.27 +/- 0.04 MJ.d(-1).kg(-1) corrected body mass), fat-free mass (men, 0.41 +/- 0.07 MJ.d(-1).kg(-1) FFM; women, 0.46 +/- 0.07 MJ.d(-1).kg(-1) FFM), or corrected fat-free mass (men, 0.30 +/- 0.05 MJ.d(-1).kg corrected body mass; women, 0.30 +/- 0.04 0.30 +/- 0.05 MJ.d(-1).kg(-1) corrected body mass). PAL was the same for men (3.4 +/- 0.5) and women (3.3 +/- 0.4). Energy intakes were higher (P < 0.05) in men (6.0 +/- 2.0 MJ.d(-1)) than women (4.8 +/- 1.8 MJ.d(-1)). The average minimum core temperature was 36.0 +/- 0.4 degrees C, and the mean maximum core temperature was 38.5 +/- 0.3 degrees C. CONCLUSIONS: For both men and women, total energy expenditures were among the highest observed for a military FEX. TEE, when normalized or corrected to body mass and fat-free mass, and PAL were the same for men and women.

The role of thyroid hormones in the control of energy expenditure.

Thyroid hormones have a direct effect on the basal or resting metabolic rate in man and a permissive effect on the adaptive thermogenesis of small animals, while altering the energy expended in exercise to the extent that patients with thyroid disorders exercise to a greater or lesser degree. The physiological concepts of energy expenditure need to be seen in the context of a new method for measuring 'thyroid thermogenesis'. Thyroid hormones seem, in evolutionary terms, to have developed a thermogenic role during the transition from poikilothermy to homeothermy; they are responsible for the increased heat production required for homeotherms to maintain body temperature above that of the environment. The potential mechanisms responsible for thyroid hormone-controlled energy expenditure are complex. Uncoupled oxidative phosphorylation is probably not responsible for thyroid hormone-controlled thermogenesis except in the special case of brown adipose tissue thermogenesis, where thyroid hormones act permissively. The concept that increased ATP generation must be coupled to ATP utilization needs to be linked with the idea that thyroid hormone-controlled thermogenesis must be through inefficient pathways of metabolism. Several of these potentially important pathways of intermediary metabolism in thyroid hormone-controlled thermogenesis can now be defined and measured, but their role in the regulation of nutritionally induced alterations in thyroid status and thermogenesis remains to be explored.

A novel anti-dysmenorrhea therapy with cyclic administration of two Japanese herbal medicines.

PURPOSE AND METHODS: Using two Japanese herbal medicines, Shakuyaku-kanzo-to (SK) and Toki-shakuyaku-san (TS), we have evaluated a novel strong antidysmenorrhea therapy. SK/TS cyclic therapy, in which the herbs are administered alternately within the menstrual cycle. RESULTS: All of the 17 dysmenorrhea patients including recurrent endometriotic and adenomyotic patients after treatment with gonadotropin-releasing hormone agonists or danazol, obtained complete relief within three months when treated with the SK/TS cyclic therapy. Nine of 12 patients treated with the SK/TS cyclic therapy ovulated as determined by biphasic changes in basal body temperature patterns. All the three secondary ammenorrhea patients with moderate levels of serum estradiol, but not the three secondary amenorrhea patients with little serum estradiol, ovulated during the SK/TS cyclic therapy. One of the treated patients, who had a history of 10 repetitive spontaneous abortions. carried the 11th pregnancy to term resulting in a normal newborn. CONCLUSION: The SK/TS cyclic therapy can be a conservative antidysmenorrhea therapy for endometriotic and adenomyotic patients who desire pregnancy.

Temperature monitoring during photodynamic therapy of skin tumors with topical 5-aminolevulinic acid application.

Temperature monitoring during photodynamic therapy (PDT) with topical 5-aminolevulinic acid (ALA) cream application was performed on 22 patients with solar keratoses (SK) and basal cell carcinoma (BCC). The lesions were located on the forehead, nose, ear and cheek. Temperature measurements during photoirradiation, with a power density of 100 mW/cm2 from an incoherent light source (light delivery system for PDT), were carried out by noncontact (infrared thermal imaging radiometer) and contact (thermocouple) methods. Thermal imaging analysis revealed nonuniform temperature distribution in the irradiated areas. The temperature gradually increased from the peripheral to the central zone of the area. The results showed that photoirradiation induced heating of the skin tumors to 39.5-42.5 degrees C during the PDT procedure. The temperature of normal skin areas disposed symmetrically to the lesions on the contralateral side at the same conditions of irradiation (without prior ALA application) was about 42-43.5 degrees C. The surface temperature differences (delta T) between the normal and tumor tissues after 10 min of irradiation were 3.3 +/- 0.5 degrees C in the forehead areas, 2.5 +/- 0.4 degrees C in the nose areas and 0.8 +/- 0.3 degrees C in the ear areas.

Classical and "true" gestational postmaturity.

In a study of a sample of 317 conceptional basal body temperature (BBT) curves obtained from normal women, the authors have applied new definitions of prematurity and postmaturity which take into account the time of ovulation. They were thus able to estimate (1) the error rates associated with the classical definitions-incorrect classification as pre- or postmature and nondetection; in particular, for this series, the percentage of incorrectly classified postmatures is high (70 per cent) and is even more so when considering only the unwanted births (80 per cent); (2) the order of magnitude in terms of days of the error made in assessing postmaturity by the classical method. This was found to be quite substantial for the misclassified cases.

[Adaptations in reproduction and behavior of captive chimpanzees-- zoobiological and veterinary managements].

Monitoring of renal LH-excretion, changes in genital tumescence and menses assesses reproductive status in zookept female chimpanzees. Temporary detumescence of female sex skin in estrus is a reliable indicator for stress. Assessment of female chimpanzee reproductive status relates to local and individual variation of cycle length and temporal correlation of investigated parameters. Monitoring of neonate chimpanzee behavioural ontogeny is an essential tool of evaluating applied rearing methods since individuals were to be integrated into the adult group during adolescence. Slow and continuous transition periods between consecutive rearing phases avoid irreversible disturbed behaviour. Care by one person up to the age of 12 months, followed by a 3 year stay in a peer group guarantee normal development in zookept infant chimpanzees. 4-5 years old chimpanzees with infantile attributes and abilities to submit and appease can be integrated to adults with low risk. In female gorillas sexual cyclicity was monitored by renal excretion of LH, length of menses, sexual behaviour and--in tame females--by basal body temperature and variation of length of the urogenital cleft. Intraspecific variation of cyclicity allowed individual fertility assessment after comparison of several cycles. Analyses of behaviour gave hints to overcharged adaptability and reduced infertility under inadequate maintenance. Data on semen and testicular biopsy improve fertility evaluation in gorilla males and point to degree and time of tissue alteration and etiology. Body hygiene analogous to the human, tool use and interspecific play with chimpanzees and humans behind window screens were observed in inadequately kept gorillas. Homosexual behaviour among females was reversible with environmental and social changes. Coalitions among nonrelated females were an effective social strategy against an aggressive male. Cyclicity was disturbed drastically by social events such as physical lesions made by a male but normalized with improved social situation. Disturbed cyclicity featured prolongation of interestrus intervals and complete detumescence, oligomenorrhea and amenorrhea. Nulliparous females in their third decennium needed more than 1.5 years of social contact to a fertile male to become fullterm pregnant. During the first two months of pregnancy stillbirths and embryonic resorptions were detected. Handreared and inexperienced primiparous gorilla females accepted their infants and reared them normally after witnessing motherrearing in neighbored chimpanzee females for several years. Opportunities of free choice and decision making determine zookept pongid behaviour, that cannot be compared with prisoners' ethology. Adaptations of ontogenetic behaviour and reproduction, teleonomic patterns and zoomorphism are of zoobiological relevance. Adaptations develope during prolonged periods of time and thus results of corresponding management issues are to be assessed a posteriori.

[Preliminary study on 4 indices of basal body temperature in the evaluation of luteal phase insufficiency after clomiphene treatment].

The luteal phase insufficiency after Clomiphene treatment in 90 patients with polycystic ovary syndrome (PCOS) and other menstrual disorders was evaluated by four indices of BBT. The four indices of BBT are (1) BBT curve classification; (2) High phase score (HPS); (3) Planimetric nidation index (PNI); (4) Length of follicular phase. 90 patients (248 cycles) were divided into two groups: non-pregnant group (214 cycles) and pregnant group (34 cycles). The result indicated that 70% cycles of non-pregnant group, the types of BBT are type III-VI, HPS is less than 9; the mean value of PNI is 45.7; the follicular phase lists beyond 17 days, with a mean of 18.6 days. More than two-thirds of the study cycles are abnormal at least in two indices. In all cycles of the pregnant group, BBT curve are of type I, II, HPS greater than 9, PNI greater than 57. The results suggest that measurement of the four indices of BBT is a simple method which could be widely used for the evaluation of luteal phase insufficiency.

Controlled study of bromocriptine and placebo for induction of ovulation in normoprolactinemic secondary amenorrhea.

In order to evaluate the effect of bromocriptine in the treatment of secondary amenorrhea, a double-blind placebo-controlled study including 30 women with normo-prolactinemic normo-hypogonadotropic hypogonadism was carried out. The patients were given either 5 mg bromocriptine or placebo every day for 12 weeks and observed during the following 3 months. A biphasic basal body temperature curve and serum progesterone levels exceeding 25 nmol/l during the expected midluteal phase were considered an indication of ovulation. Restoration of ovulation was observed in 2 of 17 women given bromocriptine and 4 of 13 women given placebo. Bromocriptine was found to have no specific effect on the restoration of ovulation in women with secondary amenorrhea and normoprolactinemic normo-hypogonadotropic hypogonadism.

Effect of pindolol on hormone secretion and body temperature: partial agonist effects.

Pindolol has been shown to be a partial agonist at 5-HT1A receptors in preclinical studies. It has also been reported to inhibit the effects of other 5-HT1A partial agonists such as ipsapirone and buspirone on hormone secretion and body temperature in man, indicating its antagonist action at 5-HT1A receptors in man. To determine if pindolol has 5-HT1A agonist as well as antagonist effects in man, pindolol, 30 mg, p.o. and placebo, were given single blind in random order to 23 normal men with indwelling venous catheters and its effects on hormone secretion and body temperature noted. Pindolol significantly increased basal plasma cortisol concentrations, whereas it decreased plasma prolactin (PRL) concentrations and body temperature. The increase in plasma cortisol due to pindolol suggests a 5-HT1A agonist action and is consistent with a 5-HT1A partial agonist mechanism in man whereas the PRL effects are consistent with an antagonist action at 5-HT1A receptors. The effects of pindolol on plasma cortisol concentration and body temperature were significantly negatively correlated. Furthermore, these results indicate significant differences in the 5-HT1A-dependent regulation of PRL and the hypothalamo-pituitary-adrenal (HPA) axis and body temperature, and suggest that human basal PRL secretion is tonically stimulated by 5-HT1A mechanism whereas the HPA axis and body temperature are not. Since rodent studies suggest differences in 5-HT1A receptor sensitivity between males and females, the results reported here need to be replicated in females. These differences in the effect of pindolol are discussed in terms of receptor reserve theory.
