We carried out this work with the purpose of studying the effects of protein and vitamin B deficiency on the morphologic and quantitative aspects of the myenteric plexus of the descending colon of adult Rattus norvegicus. Twenty-eight rats were divided in two groups, one of them receiving chow with 22% protein level (control) and the other fed with chow having 8% protein level without vitamin B...

The incidence of complete regression of Sarcoma 180 (S-180) in vitamin He-deficient Swiss mice was significantly reduced in ani mals thymectomized 1-5 days after birth but not in shamthymectomized mice, neonatally thymectomized mice implanted s.c. with thymus autografi«,mice thymectomized 9 or 30 days after birth, or neonatally splenectomized mice. The initial retardation of the growth of S-18...

Kline, Keenan, Elvehjem, and Hart (1) have described a syndrome produced in chicks by feeding a heated diet of natural foodstuffs. Elvehjem and Koehn (2) have described the preparation from liver of a concentrate which will prevent the syndrome. The concentrate was prepared from an aqueous extract of liver from which the flavins had been removed by adsorption on fullers’ earth and filtration. I...

In a previous investigation 2 the writers studied the vitamin B content of poultry flesh and eggs. In this paper they report the results of experiments conducted with rats for the purpose of determining the vitamin A value of the body flesh and fat of several species of domestic fowl. These tests were made on fowls reared under ordinary conditions and fed rations which were in general use. The ...

There are two general types of metabolism experiments: those of relatively short duration covering several periods, each from a few days to a week in length; and those carried out over as long a period as possible. As examples of the first type we have such investigations as the study of the effect of a given substance upon the nitrogenous equilibrium, or the study of the ability of the animal ...

Since it has been shown (1, 2) that inositol will cure alopecia in mice which have been fed a diet devoid of this factor, a study of the antialopecia action of related compounds seemed advisable. Such a study of specificity was of special interest in the case of inositol, because this substance presents a unique case among water-soluble vitamins. While close chemical relatives of the other vita...

MS is a rare neurodegenerative disease with an immunopathological background. Although, it has rather low global prevalence, can be considered among one of the most common youth disabling disorders that are not related to trauma. It also classified as complex many susceptibility genes incriminated in its etiology and prognosis. In addition, several well identified extensively studied environmen...

I n the experiment reported here an attempt has been made to determine whether rats offered a free choice between two compound diets, identical except in their starch content and both deficient in the vitamin B complex, would select the one on which they could synthesize the required vitamins by refection. In the process of refection, first investigated by Fridericia (1926), rats are able to ut...

The vitamin B 2 content of foods has historically been determined as total riboflavin (TRF), and the most common method of TRF analysis has been the AOAC standard fluorometric procedure. A modification of this method to permit the use of flow injection analysis (FIA) is reported here. A number of foods were analyzed and the results generally agreed with the published values. However, the standa...

Nutritional status of sixty women, who were either marginal farmers or landless agricultural workers were assessed by diet survey, anthropometry and estimation of haemoglobin levels. Diet survey carried out by the 24 hour recall method revealed adequate intake of calories and protein but low intake of micronutrients. While intake of vitamin C and the B vitamins were poor, iron and vitamin A wer...
