INTRODUCTION: Imedeenô is a cosmeceutical that provides nutrients to the skin. One of its active ingredients is the Marine Complexô (MC). AIM: The aim of this study was to evaluate whether MC affects skin morphogenesis differently in female and male human skin equivalents (HSEs). METHODS: Human skin equivalents were established with cells obtained from female or male donors between 30 and 45 years of age and cultured for seven or 11 weeks in the presence or absence of MC.

The naturally occurring tetrapeptide acetyl-N-Ser-Asp-Lys-Pro (AcSDKP) recognized as a potent angiogenic factor was shown recently to contribute to the repair of cutaneous injuries. In the current article, we report the ability of AcSDKP to exert a beneficial effect on normal healthy skin and scalp and to compensate for the ageing process. In vitro AcSDKP at 10?ππ-10?? M significantly stimulates the growth of human keratinocytes, fibroblasts and follicle dermal papilla cells.

Specimens of newt, Triturus cristatus carnifex (Laurenti), anesthetized by submersion in 0.2% chlorbutol in tap water for 15 min, and then placed out of water in a damp terrarium, show hypertrophy of the spleen that in 2 hr gradually increases from 0.31 +/- 0.12%with respect to body weight to 1.56 +/- 0.26% (means and standard deviation calculated for groups of six animals). Other anesthetics either do not produce hypnosis (Veronal), do not have a prolonged enough effect (ethyl ether, chloroform), or induce vasodilatation, which prevents hypertrophy (MS-222, urethane).

Pain

Hypnosis and acupuncture can alleviate experimentally induced pain but the mechanism of analgesia remains unclear for both techniques. Experimental pain was induced by cold pressor test (CPT) in 8 male volunteers. Analgesic effect of hypnosis (HA) and acupuncture (AA) was assessed before and after double-blind administration of placebo or naloxone, in a prospective, cross-over study. We found that pain intensity was significantly lower with HA as compared with AA, both with naloxone (P less than 0.001) and placebo (P less than 0.001).

OBJECTIVES: The issues of differential effects among cognitive strategies during hypnosis in the control of human pain are under active debate. This study, which employs measures of pain perception, electrocortical and autonomic responses, was aimed at determining these pain-related modulations.
