Bacteriologic Exmanination of Guinea Pig Mammary Gland: Preliminary Report

The uptake of doubly labeled chylomicrons by guinea pig mammary gland and liver.

Histological Changes in the Pregnant, Lactating and Involuting Mammary Gland of the Guinea Pig

The histological changes of mammary glands ofguinea pigs during mid and late pregnancy, 1 day after parturition, peak lactation and 2, 3, 4, 8 and 12 days after weaning were studied. Rapid growth of the glandular tzssue occurred towards late pregnancy and was completed by peak lactation. Plasma cells occurred in large numbers in the interalveolar connective tzssue during the period between mid-...

Esterification of glycerol 3-phosphate in lactating guinea-pig mammary gland.

1. The presence of palmitoyl-CoA-l-glycerol 3-phosphate palmitoyltransferase (EC 2.3.1.15) has been demonstrated in a particulate fraction of mammary tissue from lactating guinea pigs. 2. Cell-free preparations also catalysed the activation of palmitate and oleate, and the conversion of enzymically formed phosphatidic acid into glycerides, in accord with the Kennedy pathway of glyceride formati...

Karyotype of Hairless Guinea pig

Chromosomal patterns of experimental animals are useful tools for cytogenetics research and animal breeding. Chromosome investigations of the hairless guinea pig are rare, therefore, karyotype of hairless guinea pigs (twelve male and female) was studied using metaphase spreads of bone marrows and G banding techniques. The chromosomes diploid number was 2n= 64 and polymorphism of three type chro...

The control of some oxidative pathways in guinea-pig mammary-gland mitochondria.

1. Human synovial fluid was analysed electrophoretically before and after treatment with testicular hyaluronidase. 2. After hyaluronidase treatment, the electrophoretic mobilities of the synovial proteins decreased markedly and were similar to the values obtained for blood serum proteins. 3. The 1r-component, a complex of hyaluronic acid and albumin, could not be detected after hyaluronidase tr...
