A method to estimate the somatic cell count of milk from a mastitic quarter using composite somatic cell count.

The purpose of the study was to estimate the extent to which one quarter could be inflamed relative to the other three quarters of a cow, given that knowledge only of the composite milk somatic cell count (SCC) was available. An algebraic relationship, which incorporated the parameters of composite milk SCC, production loss associated with composite milk SSC, SCC of milk from an inflamed quarter, and SCC from three non-inflamed quarters, was used to derive hypothetical estimates of the SCC in one inflamed quarter. A simple case was considered in which one quarter was mastitic, the SCC in milk of the noninflamed quarters was equal, and there was no production compensation by the noninflamed quarters. Previously published estimates were used for production loss associated with composite milk SCC. For moderate composite milk SCC (300,000-500,000 cells/mL) and low-to-moderate SCC in milk of noninflamed quarters (100,000 cells/mL), the SCC of milk from one inflamed quarter was predicted to be very high, ranging from about 1.26 million (log10 SCC = 6.1) to 6.3 million (log10 SCC = 6.8) cells/mL, and compatible with signs of clinical mastitis. These results suggest that in order to screen cows with clinical mastitis in only one quarter, composite milk SCC should be considerably lower than values presented previously by other investigators.

[The painful body of the psychotic. A balance between psychiatric symptoms and somatic diseases in somatic patients].

This paper revises the medical and psychoanalytical studies approaching the relationship between physical and psychiatric symptoms in the psychotic patient, with special attention to P. Marty, A. Andréoli and C. Dejours works. The authors report two patients suffering from mood disorders whose psychiatric symptoms disappeared when a pneumonia appeared. They also present two psychotic patients who has been treated for several years with description of the oscillation between psychiatric and physical symptoms. Psychiatric symptoms in psychosis permit a discharge way of the psychic excitement that provides a protective effect against somatic disorders. The effectiveness of ancient or modern psychiatric therapeutics is partially based on their body effect (like hypoglicemics in Sakel therapy, seizures in E.C.T., fever in malaria therapy, iatrogenic parkinsonism in neuroleptic treatment). Human physical illness allows body cathexis and reorganization of the psychic life.

Assessment of genotoxic effect of piperine using Salmonella typhimurium and somatic and somatic and germ cells of Swiss albino mice.

Piperine (CAS 94-62-2) is a constituent of various spices and is used as a common food additive all over the world. The genotoxic potential of piperine was assessed using four different test systems, namely, Ames test using Salmonella typhimurium, micronucleus test, sperm shape abnormality test and dominant lethal test using Swiss albino mice. In the Ames test, six different doses of piperine, in the range of 0.005-10 mumol/plate, did not induce his+ revertants, with or without metabolic activation, indicating its nonmutagenic nature. In the bone narrow micronucleus test using two doses in the range of therapeutic usage (10 and 20 mg/kg body weight), piperine itself was non-mutagenic. Like in somatic cells, piperine (10 and 50 mg/kg body weight) failed to induce mutations in male germ cells of mouse as assessed by using the sperm shape abnormality and dominant lethal tests. Piperine thus appears to be a non-genotoxic chemical.

Somatic embryogenesis in pumpkin (Cucurbita pepo L.): control of somatic embryo development by nitrogen compounds.

Embryogenic cultures of pumpkin (Cucurbita pepo L.) were initiated from mechanically wounded mature zygotic embryos on 2,4-D-containing MS medium, and on hormone-free, semisolid modified MS medium containing NH4Cl as the sole source of nitrogen. The habituated line was derived from the embryogenic tissue induced with 2,4-D and maintained on medium without growth regulators. Sustained subculturing of the three embryogenic lines on a medium with NH4Cl as the sole source of nitrogen enabled the establishment of highly uniform cultures in which no further development into mature embryo stages occurred. The tissue consisting of proembryogenic globules or globular stage embryos was maintained, without decline, for over six years. Globular embryos proceeded to maturity when a combination of reduced (NH4) and unreduced (NO3) forms of nitrogen was provided in the medium. Different nitrogen sources in the medium caused changes of medium pH during subculture in the pH range of 4.0-6.5. The tissue growth and embryo development were blocked on medium with pH adjusted and stabilized at 4.0 or at 3.2.

Psychic and somatic anxiety: worries, somatic symptoms and physiological changes.

Contrary to self-reports, patients with generalized anxiety disorder exhibit increased muscle tension but not autonomic hyperarousal. Under stress they tend to react autonomically in a less flexible manner than normal controls. There is only a weak relationship, and in some instances a desynchrony, between physiological changes and perception of change. The inconsistencies between self-reports of physiological states and physiological recordings can be explained by alterations of body sensations through psychological factors, predominantly expectations of and attention to bodily states, that lead to perceptual distortions.

Interrelationships of somatic cell count, mastitis, and milk yield in a low somatic cell count herd.

In a high yielding low SCC herd, changes in milk yield associated with SCC and occurrence of clinical mastitis and differences in SCC with parity, clinical mastitis, and DIM were investigated. Milk yield data were obtained at every milking, and SCC was measured once every 48 h in 117 cows during the first 119 d postpartum. Effects of SCC and clinical mastitis on cumulative milk yield in the first 119 d postpartum were evaluated with least squares linear regression. Repeated measures ANOVA was used to detect changes in SCC. The SCC was highest at lactation onset, and cows with clinical mastitis had significantly higher SCC. During the 10 d prior to onset of clinical mastitis, SCC was higher in affected cows than in matched unaffected controls and surged just prior to diagnosis. During the 10-d period following a mastitis treatment, SCC differences between treated and control cows remained significant but became smaller with time and returned to the premastitis differences. Occurrence of clinical mastitis was associated with 5% milk yield loss. Cows with mean SCC > 245,000 cells/ml over the 119 d showed 6.2% yield loss compared with cows with SCC < or = 90,000 cells/ml. Cows with clinical mastitis had higher SCC prior to and following the end of treatment for mastitis than did controls. Clinical mastitis and SCC were associated with significant yield loss. Milk yield loss attributed to clinical mastitis was greater than that associated with elevated SCC (> 245,000 cells/ml) because a greater percentage of cows (26%) had clinical mastitis than elevated SCC (12.5%).
