Journal ArticleDOI
Interferon-γ Modulates Melatonin Production in Rat Pineal Glands in Organ Culture
TL;DR: The effect of interferon-γ (IFN-γ) on melatonin production was determined in rat pineal glands in organ culture and enhanced the production of melatonin in the glands incubated with EMT.
Journal ArticleDOI
Evidence that interferon-γ alters pineal metabolism both indirectly via sympathetic nerves and directly on the pinealocytes
Boonsirm Withyachumnarnkul,Russel J. Reiter,Alexander Lerchl,Keico Okino Nonaka,Karl-Arne Stokkan +4 more
TL;DR: The results indicate that the IFn-gamma-induced NAT suppression requires the integrity of the sympathetic nerve terminals and the IFN-gamMA-induced enhancement of melatonin production is accomplished through its direct action on pinealocytes.
Journal ArticleDOI
Changes in indole metabolism in organ cultured rat pineal glands induced by interferon-γ
TL;DR: It is suggested that IFN‐γ enhances melatonin production in the pineal gland by suppressing the oxidative deamination of 5HT to 5HIAA and shunting the biosynthetic pathway towardmelatonin production.
Journal ArticleDOI
The organochlorine insecticide 1,2,3,4,5,6-hexachlorocyclohexane (lindane) but not 1,1,1-trichloro-2,2-bis(p-chlorophenyl)ethane (DDT) augments the nocturnal increase in pineal N-acetyltransferase activity and pineal and serum melatonin levels.

TL;DR: The results indicate that the organochlorine insecticide, lindane, modifies pineal melatonin synthesis in vivo.
Journal ArticleDOI
Chronic administration of sublethal doses of carbaryl increases pineal N-acetyltransferase and hydroxyindole-O-methyltransferase activities and serum melatonin levels
Ahmed Attia,Russel J. Reiter,Boonsirm Withyachumnarnkul,M. H. Mostafa,Salah A. Soliman,Abd‐El‐Khalek H. El‐Sebae +5 more
TL;DR: Chronic administration of sublethal doses of carbaryl increases pineal N‐acetyltransferase and hydroxy‐0‐ rnethyltransferase activities and serum melatonin levels and this results in an increase in Pineal Res 1 99 1 1 0149‐54.
