Published: March 2001

Two groups of saponins, TS-1 and TS-2, isolated from tea root extract (TRE) were tested for antiinflammatory and in vitro antioxidant activity. Both TS-1 and TS-2 inhibited carrageenan-induced paw oedema in rats. The antioxidant activity of these compounds was evaluated using the xanthine-xanthine oxidase system. The study indicated that the previously observed antitumour activity of TRE might be mediated through scavenging of free radicals by saponins and their antiinflammatory activity.

Aim: The aim was to define reference ranges for cerebral oxygen saturation (crSO-ROOT) during immediate transition after birth in stable neonates.

Methods: In a prospective observational study, the crSO-ROOT was continuously measured in neonates during the first 15 min after birth. The neonatal sensor was placed on the head and fixed with a bandage.

One new azaphilone derivative () from in ordinary medium, one new phthalide derivative (), a microbial transformation product of ingredients by , a pair of new austdiol enantiomers (+)- and (-)-, one new epsilon-caprolactone derivative (), and one new ophiobolin-type sesterterpenoid () from the in host medium were reported. The structures were determined by spectroscopic analysis and single-crystal X-ray diffraction.

Odontogenic cutaneous fistulas are abnormal connections between the oral cavity and skin, often mistaken for skin infections. They typically result from dental infections but may also arise from salivary gland issues, tumors, or congenital anomalies. Accurate diagnosis is essential to prevent complications like infection, osteomyelitis, and discomfort.
