2-Aminoaryl ketones undergo smooth Friedl�nder condensation/annulation with α-methyleneketones on the surface of nanoporous aluminosilicate catalyst to afford the corresponding quinoline derivatives in good yields with high selectivity due to its high surface area, large pore volume, and high acidity. The use of highly acidic and reusable AlKIT-5 catalyst makes the Friedl�nder annulation simple, convenient, and practical. [ABSTRACT FROM AUTHOR]

Five groups of male rhesus monkeys, Gp. I--sham-vasectomized stock diet-fed (SVS), Gp. II--vasectomized stock diet-fed (VS), Gp. III--sham-vasectomized atherogenic diet-fed (SVA), Gp. IV--vasectomized atherogenic diet-fed (VA) and Gp. V--atherogenic diet-fed vasectomized monkeys (AV) were observed for a period of 1 1/2 years. Vasectomy per se had no effect on the level of serum or tissue lipids either alone or in combination with atherogenic diet feeding. Following vasectomy the involvement of aorta by fatty lesions was significantly increased and this occurred in animals of all four experimental groups when compared with the control animals. The maximum increase was noted in group IV. Again, there was a significant increase in the frequency of aortic plaques in groups II, 111 and IV while it was increased in coronary arteries of all the experimental animals (Gps. II, III, IV and V). Group IV monkeys showed higher frequency of plaques as compared to group V animals. Although the plaque height was increased in all the vessels of the experimental animals, significant differences were observed only in the coronary arteries of group II monkeys and in intra-cranial cerebral vessels of group HI animals. This study shows that vasectomy per se tends to increase atherosclerosis in rhesus monkeys. [ABSTRACT FROM AUTHOR]

Investigates the aggravation of experimental atherosclerosis in vasectomized, cholesterol-fed rabbits. Elevation of the level of plasma cholesterol following vasectomy in stock diet-fed rabbits; Increase in aortic sudanophilia, atherosclerotic plaque size and coronary atherosclerosis index in vasectomized atherogenic diet-fed rabbits as compared to their controls; Claim that pathological side effects could develop in experimental animals following vasectomy.

The article discusses the effect of chronic protein deficiency on the outcome of malaria infection in rats and immune status of these animals. The results of our study provide evidence that chronic dietary protein deprivation in rats markedly affects the course of induced parasitaemia. Amongst the animals fed a 4% protein diet 50% (17/34) had prolonged prepatent period and low levels of parasitaemia which remained patent for a few days only. The lowering of the parasitaemia due to protein deficiency could be the result of many factors which are induced as the result of secondary effects of protein deprivation.
