[Prothrombotic and prethrombotic markers in obese diabetic and non-diabetic subjects]. / Indici protrombotici e pretrombotici in soggetti obesi diabetici e non diabetici.

The Authors studied the behaviour of some prothrombotic (fibrinogen, factor VII, antithrombin III and tissue plasminogen activator) and prethrombotic (beta thromboglobulin, D-dimer) markers in a group of obese subjects in relation to various physiopathological parameters. The series consist of 93 obese subjects (29 m, 64 f, mean age 55 +/- 6 yrs, BMI 33 +/- 1), of whom 62 suffering from type 2 diabetes in good metabolic control obtained by oral hypoglycemic (42 cases) or insulin (20 cases) treatment. For each subject the Authors determined the plasmatic levels of glucose, total cholesterol, triglycerides (enzymatic method, Boehringer kits), fibrinogen (coagulometric method, Organon kit), factor VII (chromogenic method, IL kit), antithrombin III (chromogenic method, IL kit), tissue plasminogen, beta thromboglobulin and D-dimer (ELISA method, Boehringer kits). The results were examined in relation to sex, age, overweight degree, waist/thigh ratio, total cholesterol, triglycerides and, for diabetics, to the therapeutical treatment. The fibrinogen plasma levels proved statistically (0.05) increased proportionally to the overweight degree (BMI over 35), cholesterol levels (over 250 mg%) and age (51-65 yrs); factor VII showed a significant increase (0.05) related to the cholesterol levels, the overweight degree and, surprisingly, to female sex; as regards antithrombin III, its sharp reduction was related with ageing and with the "gynoid type" waist/thigh ratio; tissue plasminogen activator showed a statistically significant reduction (0.05) in the group with older age (over 65 yrs); the beta thromboglobulin levels were obviously increased (0.05) in the hypercholesterolemic and hypertriglyceridemic subjects (over 250 mg%), the D-dimer values increased proportionally with age (0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

[Elimination if living microbial contaminants in non-sterile vaccines]. / Eliminazione di contaminanti microbici vivi in vaccini non sterili.

The authors propose the use of changes of temperature for the decontamination of non-sterile vaccines. With the use of this method they have seen that the antivariolous vaccine and the typhus one, artificially polluted by hemolytic streptococci, have been brought back within the requisites required from the Italian F.U. 8th edition.
