brown alga, turbinaria conoides was successively extracted with n-hexane, cyclohexane, methanol and ethanol:water (1:1). the extracts were evaluated for antibacterial and antifungal activities by disc diffusion method. minimal inhibitory concentration was determined for active extracts by broth dilution method. the antiviral activity and cytotoxicity of the extracts were tested in human embryon...

background: the present study sought to investigate molecular evidence for association between the presence of herpes simplex virus (hsv), cytomegalovirus (cmv), and epstein-barr virus (ebv) in crc and colorectal polyp by using the pcr method in iran. methods: in this analytical case-control study, we selected 15 patients with crc, 20 patients with colorectal polyp, and 35 patients without mali...

Antigens isolated from herpes simplex virus type 1, herpes simplex virus type 2, or cytomegalovirus-transformed hamster cells were tested against 66 sera from non-cancer individuals or patients with different types of cancer. By use of the microcomplement fixation procedure to quantify all antigen-antibody interactions, it was observed that 94% (p less than 0.001) of all sera from patients with...

Herpes simplex virus infections of humans have been known since ancient times. Contemporary society has witnessed a series of devastating manifestations of herpes simplex virus infections--namely, genital herpes simplex virus infection and neonatal herpes simplex virus infection. With the evolution of society, particularly advances in birth control and increasing promiscuity, the seroprevalence...

BACKGROUND Pulmonary pathogenicity of herpes simplex virus type 1 in patients in intensive care without classic immunosuppression as well as the necessity of antiviral treatment in the case of herpes simplex virus detection in respiratory specimens in these patients is controversial. We present a case of acute respiratory distress syndrome in a patient with stable chronic lymphatic leukemia not...

herpes simplex virus (hsv) is one of the common pathogenic viruses of humans bing. this study aimed to determin anti-herpes virus activity of mentha piperita extracts in vitro. mentha piperita extracts can inhibit hsv infection when the cells treated before viral adsorbtion. hsv-1 were also inhibited by menthol after viral adsorption. hsv-1 viral particles were directly inhibited and viral yiel...

background and aims: herpes simplex virus (hsv) is responsible for several significant human viral diseases, with severity ranging from subclinical to fatal infection. herpes simplex virus type 2 (hsv2) infections are more commonly seen in association with the genitalia and surrounding areas, and can be transmitted to newborns during childbirth. generalized infections in newborns are also predo...

A new compound, 9-(3,4-dihydroxybutyl)guanine, has been synthesized and its antiherpes activity determined. 9-(3,4-Dihydroxybutyl)guanine was selectively phosphorylated by herpes simplex virus thymidine kinase and had a high affinity for this enzyme, with an inhibition constant of 1.5 microM. In cell culture, replication of different strains of herpes simplex virus types 1 and 2 was inhibited t...
