Human maternal and fetal serum insulin and growth hormone (HGH) response to glucose and leucine.

Maternal and fetal serum insulin and HGH responses to glucose, leucine, and glucose plus leucine were examined by infusions to pregnant women at term immediately before cesarean section. Leucine (15 gm.) with glucose (50 gm.) administered for 30 minutes to the mothers stimulates markedly maternal and fetal insulin secretion while infusion of glucose (50 gm.) causes a lower insulin response. When infusing glucose alone we noted that the duration rather than the degree of hyperglycemia determined the fetal insulin response. In fact, when glucose is given to the mother for 60 minutes the fetal insulin response is higher than when the same dose is infused for 30 minutes. Maternal infusion of leucine (15 gm.) for 30 minutes elicits only a very slight increase of insulin secretion in the mother and no change in the fetus. None of the infusions causes any alteration whatsoever in either maternal or fetal HGH secretion.

Effect of glucose priming on insulin response in the premature infant.

Our paper deals with premature infants in the first twenty-four hours of life and reports the effect of a preinfusion of glucose on glucose administration. Glucose infusion (2.5 gm.) resulted in a slight elevation of serum insulin. When this administration of glucose was preceded by a two-hour infusion of glucose, there was a striking increase in serum insulin.

In vivo treatment with a monoclonal antibody to interferon-gamma neither affects the survival nor the incidence of lupus-nephritis in the MRL/lpr-lpr mouse.

The effects of the in vitro treatment with a mAb (DB-1) that neutralizes mouse IFN-gamma on the development of the SLE-like syndrome in MRL/lpr-lpr (MRL-lpr) mice were studied. The results show that the i.p. administration of 2.6 mg/week of DB-1 from the 12th to the 20th week of age neither affected the survival nor the incidence and severity of lupus nephritis in MRL-lpr mice. This study argues against the pathogenic relevance of IFN-gamma in this experimental model of human SLE.

[Diagnostic problems in adenocarcinoma of the endometrium in women less than 40 years of age].

Endometrial adenocarcinoma in women under the age of forty presents a different course according to its histology. Adenocarcinomas of the endometrium may be classified into 4 main types: type 1, homologous or endometrioid; type 2, fallopian-like; type 3, cervical-like; type 4, unclassifiable. The majority of homologous adenocarcinomas have a relatively benign course, whereas the other types are definitely malignant. There is no room for doubt between adenocarcinoma and atypical endometrial hyperplasia in women under forty unless the histological pattern is of the homologous or endometrioid type, because the other patterns are definitely malignant.

[The treatment of nasal polyposis with the neodymium-YAG laser].

Recurrent nasal polyposis is one of the most common problem in clinical rhinology. The authors describe the anatomic and functional results obtained by Nd:Yag laser procedures performed on 47 patients, with recurrent polyposis. The use of Nd:Yag laser under local anaesthesia, by means of a rigid fiberscope, permitted to obtain a well limited excision of the pathological tissue with respect of nasal physiology. At the end no nasal packing was used because unnecessary. The authors explain the details of the method and the results obtained, pointing out this well tolerated treatment, even when repeated, taking care, in the same time, the different pathogenesis of disease.
