Erythrocyte individual phospholipids and erythrocyte membrane fluidity in subjects with vascular atherosclerotic disease with and without diabetes mellitus of type 2.

In a group of 12 subjects (5 men, 7 women) with vascular atherosclerotic disease (VAD) and in a group of 17 subjects (9 men, 8 women) with VAD and with non-insulin dependent diabetes mellitus (NIDDM) we evaluated the red cell membrane individual phospholipids and their relationships with the erythrocyte membrane fluidity. Examining the group of non diabetic subjects with VAD, it is evident that no difference is present between normals and this group regarding individual phospholipids; in this group is present a slight correlation between the erythrocyte membrane fluidity (expressed as Iex/Im ratio) and phosphatidylethanolamine only. Examining the group of VAD subjects with NIDDM it is evident that between normals and this group a significant difference is present for phosphatidylcholine and phosphatidylserine; in this group no relationship is evident between red cell membrane individual phospholipids and Iex/Im ratio.

[Behavior of pepsin in childhood and its correlation with gastric acid secretion].

Little attention has been given to the gastric secretion of pepsin in children. The purpose of this paper is to define the behaviour of peptic concentration (UI/ml) and Basal (BPO) and Stimulated (SPO) Peptic Outputs in children with normal and altered gastric acid secretion. 54 children, aged 15 months to 12 years, were studied: 20 of them were normal, 20 had gastric hypersecretion and 14 were hyposecretors. In the normal subjects the BPO is inversely correlated with age, while the SPO increases with the body weight, but this increment diminishes after the age of 6 years. From these data one can assume that the gastric principal cells reach their functional maturity around the age of 6 years. In the hypersecretors peptic and acid secretions are not correlated in basal conditions, while after pentagrastrin stimulation peptic secretion is greater than in normal subjects but not as the acid one. The SPO is correlated with body weight and height. The different behaviour of hydrochloric acid and pepsin is probably due to the use of pentagrastrin, which is a specific stimulant of oxyntic but not of principal cells. In the hyposecretors both BPO and SPO are lower than in normal children and no correlation was found with age, body weight and acid secretion.

[Changes in aerobic bacterial flora in the oral cavity of subjects with neoplasms of the head and neck area undergoing antiblastic therapy].

The AA. refer their experience about the oral bacterial flora change in patients with malignant diseases regarding to cervic - cefalic district . An increase of Lactobacilli and cariogenic Streptococci was showed in telecobaltotherapy patients, but not in patients chemotherapy treated. Therefore the AA. conclude that the radiotherapy is the most important treatment in these subjects .
