[Cytological study of an inflammatory type Pap-test].

The paper reports the results of the study of 900 s of which 630 were of an inflammatory type (70%). The age group most severely affected by phlogosis was that between 35-45 years old with the highest frequency in the group aged between 35-39 years old. Associated pathologies were found in 191 cases (21.2%), with bacterial infections in 101 cases (11.2%), candida in 43 cases (4.8%), T.V. in 17 cases (1.9%), viral infections in 10 cases (1.1%), CIN in 14 cases (1.5%) and malignant tumours in 2 cases (0.22%).

Complement activation in diabetes mellitus.

To see whether or not there is complement activation in patients with diabetes mellitus, we investigated the plasma concentrations of C4, C3, C4a, C3a and SC5b-9 in either juvenile or adult onset insulin-dependent (IDDM) and non-insulin-dependent (NIDDM) diabetic patients at least 2 years after diagnosis. C4, C3, SC5b-9 plasma levels were not significantly different in IDDM and NIDDM patients than in age-matched controls. Anaphylatoxin peptide conversion product C4a, but not C3a, was found significantly higher in adult-onset IDDM patients than in patients with juvenile onset IDDM, NIDDM patients and age-matched controls. Complement activation did not appear to be correlated with the metabolic control, nor the duration of disease nor the presence of circulating antibodies (including islet cells (ICA), insulin (IA), thyroid microsomal (TMA), and thyroglobulin (TGA)). Although there are many factors that may trigger complement activation, we found the highest levels of C4a in elderly subjects (both diabetics and control subjects) and particularly in those who had clinically detectable vascular complications.

[Cases of endometrial hyperplasia diagnosed at a regional hospital in the Province of Pavia].

Two hundred and fourteen cases of endometrial hyperplasia were diagnosed at the Hospital of Casorate (USSL 77, Pavia) between 1 january 1984 and 31 december 1989. Cases were subdivided as follows: 60 glandular hyperplasias, 54 glandular cystic hyperplasias, 83 adenomatous glandular hyperplasias, 13 atypical glandular hyperplasias and 24 cases of endometrial cancer. The analysis of data shows an increase in hyperplasia, but only the adenomatous and atypical varieties have a potentially carcinomatous evolution.

[Short term post-surgical prophylaxis in gynecology. Use of cefonicid].

In this study the Authors have evaluated the use of cefonicid in "short-term" post-surgical prophylaxis in gynecology. No effects, nor alteration to hematochemical parameters related to the administration of this medicine have been observed and the analysis of data shows that the use of cefonicid contributes to reducing the incidence of post-surgical infections in hospital in a cure group compared to a control group.

[Regulation mechanisms in prolactin secretion. Possible role of the hypophyseal renin-angiotensin system].

Recent studies have shown a possible role of different factors in the regulation of prolactin secretion. In fact many neurotransmitters (dopamine) and peptides can modulate prolactin release from anterior pituitary lactotrophs. In vitro and in vivo studies, Angiotensin II has been shown to increase prolactin release. On the basis of these data we have studied the effects of enalapril (ACE-Inhibitor) on baseline plasma prolactin in nine hypertensive post-menopausal women. The results indicate that 15-day inhibition of angiotensin-converting enzyme by enalapril significantly reduced serum prolactin levels. These data suggest that the Angiotensin II may play a role in the control of prolactin secretion in hypertensive women.

Spectral analysis of heart rate variability in the assessment of autonomic diabetic neuropathy.

We studied heart rate variability in 49 uncomplicated diabetics (27 with insulin therapy; 22 with oral hypoglycemic agents) and in 40 age-matched controls. An automatic autoregressive algorithm was used to compute the power spectral density (PSD) of beat by beat RR variability derived from the surface ECG. The PSD contains two major components (a low frequency approximately 0.1 Hz (LF) and a high frequency, respiratory linked, approximately 0.25 Hz (HF] that provide, respectively, quantitative markers of sympathetic and vagal modulatory activities and of their balance. As compared to controls, in diabetics, besides a reduced RR variance at rest (2722 +/- 300 and 1436 +/- 241 ms2, respectively), we observed during passive tilt an altered response of spectral indices of sympathetic activation and vagal withdrawal, suggestive of a complex modification in the neural control activities. In addition, we compared this approach to the commonly used clinical tests score, and observed that the latter provides overall results similar to those obtained with spectral changes induced by tilt (r = 0.42; P less than 0.01). Of potential clinical importance is that the data obtained with spectral analysis appear more thoroughly quantifiable and do not require the active collaboration of the patients.

Prolactin lowering effect of dihydroergokryptine in rat and in man.

The prolactin lowering activity of dihydroergokryptine was investigated both in rats and in humans. The drug was administered orally at the doses of 0.2, 1 and 5 mg/Kg to intact or reserpinized male rats. Nine male adult volunteers were given 300 mg cimetidine iv 90 min after receiving 2, 3 or 4.5 mg of dihydroergokryptine and 3, 4.5 and 6.75 mg of dihydroergocristine or placebo per os in a randomized, cross-over design. Eight young adult males were injected im with 10 mg sulpiride 120 min after randomly receiving dihydroergokryptine 2.5 and 5 mg or placebo in a cross-over manner. Finally, five healthy young women were given dihydroergokryptine 2.5 and 5 mg, bromocriptine 2.5 mg and placebo in a cross-over design. Dihydroergokryptine caused a strong, long-lasting, dose-dependent fall of plasma prolactin concentrations in both rats and humans. Moreover, it inhibited the reserpine-induced rise of plasma prolactin in rats, as well as the cimetidine-or sulpiride-induced hyperprolactinemia in humans. Dihydroergokryptine proved twice as potent as dihydroergocristine and about half as potent as bromocriptine. Effective doses of both dihydrogenated ergot alkaloids were much better tolerated than bromocriptine.
