Four red cell enzyme systems were studied in Malaysian mothers and their newborn belonging to three racial groups, the Malays, Indians and Chinese. No significant heterogeneity was observed in the distribution of phosphoglucomutase (PGM1), adenosine deaminase (ADA), 6-phosphogluconate dehydrogenase (6PGD) and acid phosphatase (AP) phenotypes between mothers and their newborn of the three groups. Pooled mother and child acid phosphatase data show a significant heterogeneity between the Malays and Chinese, and between the Malays and Indians. This is comparable to previous studies conducted. For the placental phosphoglucomutase (PGM3) system, a significant heterogeneity was observed between the Chinese and Malays only. No significant heterogeneity was detected in the distribution of PGM1, ADA and 6PGD phenotypes among Malays, Chinese and Indians.
We have developed the methodologies for typing and family studies to establish the modes of inheritance of water buffalo red cell acid phosphatase (Acp), protease inhibitor (Pi), and group-specific component (Gc) on isoelectric focusing and albumin (Alb), red cell alpha-esterase-3 (Est-3), and catalase (Cat) on polyacrylamide gel electrophoresis. Family studies showed that Pi, Gc, Alb, and Cat are coded by autosomal genes with two codominant alleles, while Est-3 is autosomal with two codominant alleles and a recessive null allele and Acp exhibits three codominant alleles.
Samples from 378 Chinese and 259 Malay blood donors in Singapore have been studied for electrophoretic variants in 13 red cell enzyme systems and for abnormal haemoglobins. Variants were detected in 8 of the enzyme systems, and the frequencies were polymorphic for acid phosphatase, 6 phosphogluconate dehydrogenase phosphoglucomutase (locus 1) among both Chinese and Malays, and for adenylate kinase also among Malays. Rare variants were detected in the phosphohexose, NADH diaphorase and lactate dehydrogenase systems. A new GPGD phenotype and three new LDH phenotypes have been described. Electrophoretic variants of haemoglobin were more frequent among Malays than among Chinese.
The aim of our study was to see the efficacy of petroleum ether extract of Cissus quadrangularis (CQ) on development of osteopenia in ovariectomy induced Wistar rats.
