BARAK A, Beckenhauer H, Kharbanda K, Tuma D
Alcohol
. 2001 Dec;
25(2):77-81.
PMID: 11747976
Results of previous studies have shown that chronic ethanol administration impairs methionine synthetase activity and decreases S-adenosylmethionine levels in the liver, indicating interference with homocysteine remethylation. The purpose of the...

Vet Hum Toxicol
. 1998 Oct;
40(5):263-6.
PMID: 9778759
Carbon tetrachloride-injected rats were given liquid diets with and without betaine for 7 d. Hepatic lipidosis was induced by 4 daily injections of carbon tetrachloride (CCl4). Animals were killed and...

BARAK A, Beckenhauer H, Badakhsh S, Tuma D
Alcohol Clin Exp Res
. 1997 Oct;
21(6):1100-2.
PMID: 9309323
The feeding of ethanol to experimental animals results in fatty infiltration of the liver. Recent findings have shown that ethanol-induced steatosis is accompanied by a lowering in hepatic S-adenosylmethionine (SAM)...

BARAK A, Beckenhauer H, Tuma D
Alcohol
. 1996 Sep;
13(5):483-6.
PMID: 8888945
Previous studies in this laboratory have shown that feeding of ethanol to rats produces prompt inhibition of methionine synthetase (MS) as well as a subsequent increase in activity of betaine...

Alcohol
. 1996 Jul;
13(4):395-8.
PMID: 8836329
Two of the most important biochemical hepatic pathways in the liver are those that synthesize methionine and S-adenosylmethionine (SAM) through the methylation of homocysteine. This article reviews some recent findings...

Alcohol
. 1994 Nov;
11(6):501-3.
PMID: 7865151
Earlier studies by other investigators have shown that S-adenosylmethionine (SAM) has the capacity to attenuate liver injury in experimental animals. In a recent study in this laboratory, it was shown...

Hidiroglou N, Camilo M, Beckenhauer H, Tuma D, BARAK A, NIXON P, et al.
Biochem Pharmacol
. 1994 Apr;
47(9):1561-6.
PMID: 8185668
The mechanism by which ethanol impairs folate metabolism remains uncertain. In the present study, we used our new technique (affinity/HPLC) for folate analysis to study the effect of chronic alcohol...

Alcohol
. 1993 Nov;
10(6):495-7.
PMID: 8123207
Feeding rats a semiliquid ethanol diet for a period of four weeks produced a hepatic accumulation of the methylating agent N5-methyltetrahydrofolate (N5CH3THF). When the ethanol-containing diet was supplemented with 0.5%...

Alcohol Clin Exp Res
. 1993 Jun;
17(3):552-5.
PMID: 8333583
Previous studies have shown that ethanol feeding to rats alters methionine metabolism by decreasing the activity of methionine synthetase. This is the enzyme that converts homocysteine in the presence of...

. 1991 Jan;
26(2):125-8.
PMID: 1878076
Golden Syrian hamsters that have elevated hepatic alcohol dehydrogenase activity were divided into four groups and group-fed on four different liquid diets for five weeks. Group I was fed a...
