Vitamin B Deficiency

1. The histological changes of the bone marrow in fasted and rice disease pigeons are essentially the same. 2. The histological changes of the bone marrow in pure vitamin B deficiency consist of degeneration and edema and slight endothelial proliferation of the small vascular channels, but with active hematopoiesis. 3. The anemia of rice disease in pigeons is in large part a starvation anemia and not directly related to vitamin B deficiency.

A number of investigators have observed atrophy and degenerative changes in the testes of animals fed on diets deficient in the factor termed Vitamin B. Funk and Douglas (5) reported that the testicles of pigeons showing symptoms of avian polyneuritis were greatly atrophied, and that the tubules were diminished in size and contained no spermatozoa. Drummond (3) observed a similar condition in the testes of adult rats deprived of vitamin B, whilst McCarrison (8) found the atrophy of the male gonads to be very much more severe in pigeons with beri-beri than in monkeys with that disease. Allen examined the testes of rats which had been fed on Osborne and Mendels’ diet deficient in vitamin B, and found considerable derangements, to which further reference will be made in the section on Histology.

This work investigates the ability of Morinda lucida and co-administration of Morinda lucida/metformin in the control of biochemical and histological changes in alloxan-induced diabetic rats. Alloxan diabetic rats were treated with 200 mg/Kg body weight of Morinda lucida leaves extract, 1 mg/Kg BW of metformin or a combination of the two treatments for 28 days. Results of the studies revealed that Morinda lucida leaves extract significantly improved lipid profile and kidney function in diabetic rats. These positive outcomes were enhanced by combined treated with Morinda lucida leaves extract and metformin. Furthermore, the calculated atherogenic index of treated animals were close to those of normal rats as opposed to diabetic rats. Similarly, histological studies showed that Morinda lucida leaves extract and metformin administered together or singly, ameliorated damages in pancreas and kidneys from alloxan diabetic rats. It can therefore be inferred that combined treatment with Morinda lucida leaves extract and merformin could improve the potency of Morinda lucida leaves used in the management of diabetic complications

Inhibition Of Dna Synthesis

Megaloblastic anaemias are characterized by red blood cell macrocytosis. They arise because of inhibition of DNA synthesis in the bone marrow, usually due to deficiency of one or other of vitamin B12 (cobalamin) or folate, but sometimes as a consequence of a drug or a congenital or acquired biochemical defect that disturbs their metabolism, or affects DNA synthesis independent of vitamin B...

Background: Placenta is essential for maintenance of pregnancy and for promoting normal growth and development of fetus. It forms the morphological record of anatomical condition, intrauterine events and intrapartum events of gestation. Present study has been undertaken to record the data on the morphology and histology of placenta from mothers with hypertension and diabetes.Methods: This study showed several significant morphological and histological differences in the placenta of the mother with GDM and hypertensive placenta. The histological study of the placenta was done under microscope and number of syncytial knots, cytotrophoblastic cellular proliferation, fibrinoid necrosis, endothelial proliferation, calcified and hyalinised villous spots were noted per low power field in the diabetics and hypertensive group in comparison to control group.Results: All other parameters including area, thickness, diameter, and circumference of GDM placenta show a significant increase when compared with normal placenta. The gross anatomic features of placentae e.g infarcted areas, calcified areas and marginal insertion of the umbilical cord in the study group show significant increase in value (p>0.01) in diabetic and hypertensive groups when compared to that of the control or normal group.Conclusions: In present study we found that hypertensive placentae tend to be slightly smaller in size, weight, volume, area, thickness, diameter, circumference and feto-placental ratio than normal placentae but the parameters were found to be significantly greater than that of normal placentae in case of diabetic placentae. No significant differences were found in umbilical cord insertion. In normal pregnancy cases we found several histological findings which were increased in hypertensive and diabetic cases.
