OBJECTIVES Trichomoniasis is one of the most common sexually transmitted diseases in humans and is caused by the protozoan Trichomonas vaginalis. Nowadays, increasing resistance to drugs such as metronidazole resulted in many problem, so new effective remedies are needed. In this study, we evaluate constituents of essential oil and anti-trichomonas activity of Rheum ribes. MATERIALS AND METHO...

Rhubarb (Dahuang in Chinese), a well-known chinese herbal medicine, has long been used in the world and is officially listed in Chinese Pharmacopoeia which containing three species, Rheum palmatum L., Rheum officinale Bail and Rheum tanguticum Maxim. ex Balf. [1]. It is also formally listed in European and Japanese Pharmacopoeia [2,3]. This important herbal medicine has been discerned for centu...

To elucidate role of the dermomyotome in the formation of the axial skeleton, we performed extirpation and transplantation experiments on the dermomyotomes in chick and quail embryos. When the thoracic dermomyotomes of chick embryos were removed, the intercostal muscles and the distal ribs were deficient, while the proximal ribs were more or less normal. Quail tissues including the dermomyotome...

De Troyer A. The action of the canine diaphragm on the lower ribs depends on activation. J Appl Physiol 111: 1266–1271, 2011. First published July 14, 2011; doi:10.1152/japplphysiol.00402.2011.— Conventional wisdom maintains that the diaphragm lifts the lower ribs during isolated contraction. Recent studies in dogs have shown, however, that supramaximal, tetanic stimulation of the phrenic nerve...

Rheum species are medicinally important herbs, posses several type of biological activities due to the presence of anthraquinone derivatives. Several HPLC methods have been used for sepeatation of anthraquinone of Rheum Species. In most cases anthraquinones were separated using C18 column as a stationary phase, acetonitrile, water and methanol with or without acid as mobile phase at 1.0 ml/min ...

A familiarity with the anatomy of some types of bone anomalies is necessary for clinicians involved in many medical areas. The aim of this paper is to review the newest literature concerning the morphology, embryology, clinical image, and therapeutic methods of the cervical ribs in the humans. The incidence of cervical ribs has been found to vary from 0.58% in Malaysian population to 6.2% in Tu...

method for detecting lesions in the ribs, sternum and vertebrae. However, it is difficult to count the ribs as the ribs are arranged obliquely in the axial plane. With the introduction of multidetector-row CT (MDCT), the bones of thorax can be clearly examined in three-dimensional images, although the axial images are most commonly used in clinical practice. There are three known methods for co...

We propose a two-step model for the evolutionary origin of the turtle shell. We show here that the carapacial ridge (CR) is critical for the entry of the ribs into the dorsal dermis. Moreover, we demonstrate that the maintenance of the CR and its ability to attract the migrating rib precursor cells depend upon fibroblast growth factor (FGF) signaling. Inhibitors of FGF allow the CR to degenerat...
