Curcumin is a polyphenol derived from the dietary spice turmeric. The aim of this study was to investigate the in vitro effect of curcumin against eggs, cercariae, pre-adults, and adults of Schistosoma japonicum compared to praziquantel. After incubated by different concentration of curcumin or praziquantel in different time, the percent hatching rates of eggs, the percent dead rates of cercariae, and the number of dead worms were observed. Curcumin showed time- and dose-dependent schistosomicidal effects on every life stages of S. japonicum. In addition, curcumin exhibited an optimal activity against the adult stage with no differential sensitivity between male and female worms and decreased motor activity of these worms without tegumental alterations. The promising in vitro effects on all stages of S. japonicum warrants further evaluation for the prophylactic and therapeutic values in the early and late schistosomiasis in field trials.

Schistosoma japonicum is a significant public health risk in parts of China and elsewhere in Southeast Asia. To gain an insight into the epidemiology of schistosomiasis japonica, a detailed investigat...
Praziquantel, an antischistosomal compound, is used as first-line drug for chemotherapy of Schistosoma japonicum since 1984. In this article, we conducted a systematic review and mete-analysis to eval...
Schistosoma japonicum causes major public health problems in China and the Philippines; this parasite, which is transmitted by freshwater snails of the species Oncomelania hupensis, causes the disease...
Schistosomiasis, caused by blood flukes belonging to several species of the genus Schistosoma, is a serious and widespread parasitic disease. Accurate and rapid differentiation of these etiological ag...
To further investigate the importance of insulin signaling in the growth, development, sexual maturation and egg production of adult schistosomes, we have focused attention on the insulin receptors (S...
Curcumin is a commonly-used spice and food coloring. Evidence suggests that curcumin can suppress tumor initiation, promotion and metastasis in a variety of tumor cell lines. The current a...
This study is investigating the pharmacokinetic profile (i.e. the way the product is processed by the body) of a proprietary curcumin formulation compared to an unformulated curcumin produ...
Primary Objectives: 1. To evaluate clinical tolerance and response to curcumin alone and in combination with Bioperine in patients with multiple myeloma. 2. To compare the...
Heme oxygenase 1 (HO-1) serves as a protective gene. Induction of HO-1 has therapeutic potential for several indications. The inducibility of HO-1 by curcumin will be evaluated in this pil...

SCHISTOSOMIASIS of the brain, spinal cord, or meninges caused by infections with trematodes of the genus SCHISTOSOMA (primarily SCHISTOSOMA JAPONICUM; SCHISTOSOMA MANSONI; and SCHISTOSOMA HAEMATOBIUM in humans). S. japonicum infections of the nervous system may cause an acute meningoencephalitis or a chronic encephalopathy. S. mansoni and S. haematobium nervous system infections are associated with acute transverse myelitis involving the lower portions of the spinal cord. (From Joynt, Clinical Neurology, 1998, Ch27, pp61-2)
Infection with flukes (trematodes) of the genus SCHISTOSOMA. Three species produce the most frequent clinical diseases: SCHISTOSOMA HAEMATOBIUM (endemic in Africa and the Middle East), SCHISTOSOMA MANSONI (in Egypt, northern and southern Africa, some West Indies islands, northern 2/3 of South America), and SCHISTOSOMA JAPONICUM (in Japan, China, the Philippines, Celebes, Thailand, Laos). S. mansoni is often seen in Puerto Ricans living in the United States. (Merck Manual, 15th ed)
An anthelmintic with schistosomicidal activity against Schistosoma mansoni, but not against other Schistosoma spp. Oxamniquine causes worms to shift from the mesenteric veins to the liver where the male worms are retained; the female worms return to the mesentery, but can no longer release eggs.

Preclinical testing of drugs in experimental animals or in vitro for their biological and toxic effects and potential clinical applications.
