Anterior chamber tube shunt to an encircling band (Schocket procedure) in the treatment of refractory glaucoma.

We reviewed a series of 42 eyes in patients with refractory glaucoma who had undergone a Schocket procedure. The mean follow up was 17.5 months; the minimal follow up, 8 months.

Maternal and embryonic response to a "carbohydrate-free" diet fed to rats.

The effects of a carbohydrate-free, fatty acid (CF) diet on pregnant rats and their progeny were examined. A pregnant pair-fed group was included to compensate for the 40% reduction in food intake of the CF dams. Control and CF dams were killed on days 6, 8, 10, 12, or 14 of gestation.

Hematologic and trace element alterations following chronic maternal ingestion of propylthiourea.

Rats with diets containing 0.2% propylthiouracil (PTU) throughout gestation had progeny with persistent cyanosis and high neonatal mortality. Histological and histochemical studies failed to reveal lung abnormalities in these pups.

Effect of maternal protein-calorie malnutrition on fetal rat cerebellar neurogenesis.

Pregnant Sprague-Dawley rats were fed, ad libitum, diets containing either 24% (control) or 4% casein (deprived) from conception through gestation. On the 13th, 14th, 15th, 16th, 17th or the 18th day of gestation the dams of both dietary groups were injected with 2.5 mCi [3H]thymidine per gram of body weight.

Attenuating effect of zinc on abnormal placental morphology in 6-mercaptopurine treated rats.

Pregnant Sprague-Dawley rats were fed diets containing 9 (marginal level), 100 (control level), or 1,000 (very high level) ppm zinc and were given a single intraperitoneal injection of 6-mercaptopurine (6-MP, 55 mg/kg) or an equivalent volume of carboxymethylcellulose on day 11 of gestation. Live young and their placentas were recovered at surgery on day 21 of gestation: they were weighed, measured, and placentas were examined histologically. Placentas from drug treated animals were smaller in diameter and lighter in weight than controls; however, the placentas of animals fed the 1,000 ppm zinc diet were significantly heavier than those of the other drug-treated groups.

Effect of prenatal protein deprivation on fetal and neonatal thyroid morphology in the rat.

Morphogenesis of the thyroid was compared in young of control and protein-deprived rats from day 17 of gestation through the first postpartum day. Examination of histological sections revealed a significant delay in follicle formation and a reduction in gland area, follicle number, colloid space and cell size in the thyroid tissue of fetal and neonatal pups of protein-deprived dams.

Thyroid function in prenatally protein-deprived rats.

Thyroid function was examined in fetal and newborn young of dams fed diets containing 24% or 4% casein as the sole source of protein. Radioactive iodine uptake, as examined autoradiographically and by gamma counting, was significantly reduced in glands of progeny of deficient rats. Following injections of thyrotropin or thyrotropin releasing hormone, thyroid cells of newborn young of protein-deprived rats contained fewer colloid droplets than those of control pups.

Early postnatal development of the intestine in progeny of protein-deprived rats.

Development of the small intestine was studied in newborn, and 4-, 8-, and 12-day-old young of rats fed diets, during gestation, containing 24 or 4% casein as the source of protein. Newborn prenatally protein-deprived rats had shorter, narrower intestines, reduced numbers of villi per unit length, shorter villi, and reduced numbers of absorptive cells and crypt cells. These differences had disappeared by the age of 12 days in adequately fed pups that had survived to that age.
