ABSTRACT
Forty male Ile-de-France lambs (10 blocks of 4 homologous lambs) were used to study the effects of four feeding systems on muscle fatty acids (FA): raising and finishing on cool-season grasses (G), raising on the same grasses and stall-finishing, indoors, on concentrates and hay, respectively, for 22 (GSS) or 41 days (GSL), and stall-feeding indoors on concentrates and hay during both growing and finishing periods (S). Twenty-four lambs only (6 blocks) were retained for comparison of growth performances, lipid content in the longissimus thoracis muscle (LT) and their FA composition according to treatment. The 16 other lambs (4 blocks) were removed from the comparison, due to a large spread in the growth of the lambs towards the end of the trial. No significant effects of treatment were seen on the rate of growth (221, 228, 243 and 245±SE 8.0g/d, respectively, for G, GSS, GSL and S groups), and the lipid contents of the LT (2.22, 2.16, 2.17 and 2.52±SE 0.11g/100g fresh tissue). Grazing, lowered n-6 PUFA (polyunsaturated fatty acids), and increased n-3 PUFA and C18:2 c9t11 (conjugated linoleic acid cis9, trans11) compared to concentrate feeding. The main effects of grazing were not removed by a short period of finish indoors on concentrate (GSS group), but C20:4 n-6 and C22:6 n-3 contents achieved the lowest contents in this group, with significant differences from the values observed for GSL and S groups (C20:4 n-6) or from the three other groups (C22:6 n-3). After a longer period of finish on concentrate (GSL group), C18:3 n-3 (linolenic acid), C18:2 c9t11 and long chain (LC) n-3 PUFA were brought to the levels observed in the S group. In terms of adequacy for human health, the C18:2 n-6/C18:3 n-3 ratios were favourably low in the four groups (2.6, 3.6, 4.9 and 5.2±SE 0.7, respectively, for G, GSS, GSL and S groups), the level observed in the case of G group being significantly lower than for the three other groups and the level observed for GSS group being significantly lower than for the GSL and S groups.

On the basis of 144 radiation-induced intestinal and colorectal lesions seen in 109 patients, the authors review the radiologic aspects associated with such affections. Two points are emphasized: (1) the chronic and still active nature of radiation-induced injury which can explain the appearance of lesions more than 10 years after irradiation, and (2) the locoregional nature of the affection which warrants systematic exploration of the urinary tract by intravenous pyelography in addition to radiologic and endoscopic investigation of the digestive tract. The authors also advise an echography and/or CT scan to detect any neoplastic recurrence.

A case of Henoch-Schoenlein syndrome in an 8-year old child is described. The cutaneous symptoms appeared 10 days after duodenitis with ulceration of the duodenal bulb. Severe denutrition resulting from lesions of the distal ileum total required parenteral nutrition for 38 days. The anatomo-radiological signs of gastrointestinal manifestations of the syndrome are discussed.

The authors report an analytic study of hydroelectrolytic disorders in patients with APUD tumors. In most of the cases a diarrhea occurs. The type of this diarrhea is: -- a motrice diarrhea (in the great majority of carcinoid tumor and medullary carcinoma of the thyroid); -- a secretory diarrhea (W.D.H.A.): it is the case in gastrinoma (gastric hypersecretion), in secretinoma (pancreatic hypersecretion) and in vipoma (intestinal hypersecretion). The others disorders could be no diarrhea dependant (hyponatremia by ADH hypersecretion, hypercalcemia). The personal cases of the authors are: 12 medullary carcinoma of the thyroid, 19 enteraminoma and 2 others apudomas.

The authors studied the metabolism of fibrinogen labelled with iodine 125 in 57 cirrhotic patients and 25 controls. Their results show that if the 82 subjects are grouped according to biological period values (T) and plasma pool (N.I.) of each of them, 4 distinct populations emerge. In each of these 4 groups a physiopathological interpretation of fibrinogen metabolism may be proposed. In the context of consumption coagulopathies in cirrhosis, the examination is of real value and offers an objective criterion of therapeutic effectiveness.
