Sternal retractor for internal mammary artery.

A sternal retractor for easy visualization of the internal mammary artery and retrosternal area is described. We have successfully used this retractor for all internal mammary dissections without sternal or costochondral fractures in the past 6 months.

Anti-inflammatory properties of 3-methylpyrazolin-5-(4 H)-one-4-[3'-methoxy-4' (2'',3'',4'',6''-tetra-O-acetyl-beta-D-glycopyranosyl]benzylidene (compound IIIA).

Oral treatment of compound IIIA exhibited dose related inhibitory action in acute tests of carrageenan, histamine and dextran-induced oedema in rats. Marked inhibitory action of the compound was found when it was administered intraperitoneally in animals. It displayed prominent anti-arthritic activity in chronic tests of adjuvant and formaldehyde-induced arthritis in rats. It prevented the arthritis associated rise in total leucocyte count and erythrocyte sedimentation rate. It also lowered the levels of exudate volume and migration of leucocytes in carrageenan induced pleurisy in rats. It did not exhibit any analgesic, antipyretic or ulcerogenic effect. No mortality was recorded up to 2 g/kg in mice on oral or intraperitoneal treatment over a period of 72 hr.

Cytological and histochemical observations on the cortical zone of oocytes of a teleost fish, Nandus nandus (Ham).

The cortical zone of oocyte of Nandus nandus has been studied by cytological and histochemical techniques. In an early stage of oocyte development some granular substances appear in the juxtanuclear region which during oocyte growth move to the peripheral ooplasm and forms a thick cortical granular layer. Cytochemically, this cortical granular layer consists of proteins and carbohydrates along with RNA positive material, lipids, mitochondria and Golgi bodies. This cortical granular layer, later on, converts into the cortical vacuolar layer and ultimately forms the cortical alveolar structures in the vitellogenic oocyte of Nandus nandus. The results suggest that the cortical zone plays an important role in the storage of substances transported from the follicular epithelium to the oocyte. Further, the cortical granular substances which are rich in proteins, carbohydrates and lipoidal material, also help in the formation of jelly layers of the developing oocytes.

Abnormality in body curvature of Cyprinus carpio after injection of anaesthetics.

Abnormalities in the body curvatures were noticed in Cyprinus carpio after the injection of anaesthetics, viz. paraldehyde, tertiary butyl alcohol and butanol. These abnormalities occurred behind the dorsal fin and progressively developed over a period of four months. The abnormalities affect the locomotion and speed of swimming of the fish and appear to be due to toxic effects of the anaesthetics.

Silicosis in slate pencil workers. A clinicoradiologic study.

We present a study of 151 persons working in slate-pencil manufacturing industries located in the Mandsaur district of Madhya Pradesh, India. Cough, dyspnea, and pain in the chest were the important symptoms. Cyanosis, rhonchi, and crepitations were found in varying numbers of cases. The chest x-ray films were abnormal in 85 cases.
