Herpes stomatitis

In a phase 1 trial, 20 patients with advanced RCC were treated with everolimus and sunitinib grade 3 toxicities noted were herpes stomatitis, leucopenia, vomiting. Streptococcus viridans endocarditis, gastrointestinal haemorrhage, mucositis, febrile neutropenia and thrombocytopenia with bleeding. Grade 4 toxicities were anaemia and pulmonary embolism [141. 

Suggested Alternatives for Differential Diagnosis Rinderpest, infectious bovine rhino-tracheitis, bovine herpes mammillitis, malignant catarrhal fever, Peste des petits ruminants, vesicular stomatitis, bluetongue, bovine viral diarrhea, and foot rot in cattle, vesicular exanthema of swine, swine vesicular disease, and foreign bodies or trauma. 

Mechlorethamine is very irritating to mucous membranes and is especially harmful to the eyes. In patients, it causes nausea and vomiting, thromobophlebitis, granulocytopenia, thrombocytopenia, stomatitis, maculopapular skin eruption, herpes zoster, amenorrhea, azoospermia, thrombosis, bone marrow depression, tinnitis, vertigo, and hearing loss.2 LD50 (i.v., rat) 1.1 mg/kg.1...

The GH3 cell line was derived from the pituitary tumour of a 7-month-old female Wistar-Furth rat (Tashjian et al, 1968) and is used for the study of hormones. The GH3 clone produces growth hormone at a greater rate than GHl cells, a clone obtained from the same primary culture, and also produces prolactin. Hydrocortisone can be used to stimulate hormone production and also inhibits the production of prolactin (Bancroft et al, 1969). The cells are epithelial-like in morphology but can be adapted to grow in suspension culture using Eagle s MEM, under which conditions the cells continue to produce growth hormone and prolactin (Bancroft Tashjian, 1971). The cells are susceptible to herpes simplex and vesicular stomatitis (Indiana strain) viruses but not to poliovirus type 1. 

In 1986, venustatriol (2) was isolated from the red algae Laurencia venusta [5]. This compound was shown to possess many of the same structural features as thyrsiferol (1), with the exception of the stereocenters at Cig and C19 as indicated in Fig. (1). At the time of its isolation, venustatriol (2) was reported to display anti-viral activity against vesicular stomatitis virus (VSV) and herpes simplex virus type 1 (HSV-1). The absolute configuration of venustatriol (2) was verified by x-ray crystallography, an experiment that facilitated the assignment of the absolute stereochemistry of thyrsiferol (1).

Inununosuppressed radiation victims with positive serology for herpes simplex viruses are at risk for reactivation of HSV infection, with resulting clinical picture that mimics radiation stomatitis. These patients should receive prophylaxis with acyclovir or one of its congeners. If serology results are not available, patients with a history of oral or genital herpes infection should receive acyclovir prophylaxis. Patients who develop severe mucositis require assessment for HSV reactivation (2). 

The hot water extracts of bulbs and leaves of Haemanthus albiflos had strong antiviral activity against Poliovirus 1, Herpes simplex 1 virus. Vesicular stomatitis vims and simian Rotavirus SA11 (100, 101). The bulbs of this species also showed strong antiviral activity against Moloney murine leukemia virus and HIV(i02).

Pyrazomycin. Pyrazomycin (11), 3-(l-p-D-ribofuranosyl)-4-hydroxypyrazole 5-carboxamide, is isolated from S. Candidas (1—4,9,10). The incorporation of [2-13C]acetate and [1- and U-14C]glutamate into the four contiguous carbons of pyrazomycin has been reported (11,12). Pyrazomycin 5 -phosphate inhibits orotidylic acid decarboxylase. Pyrazomycin inhibits adenosine phosphorylation and decreases the incorporation of deoxyuridine into DNA of Novikoff hepatoma cells in culture. It also inhibits the growth of tumor cells and the cytopathic effects of vaccinia, herpes simplex, vesicular stomatitis, Newcasde disease, measles, Sindbis, polio, hepatitis A, and coxsackie viruses (13,14). The inhibitory action of (11) on viral multiplication is reversed by uridine. 

The trienamide onnamide A (43) is a metabolite isolated from the marine sponge Theonella sp. found in Okinawan waters [84]. It belongs to the pederin family like mycalamides and theopederins [85], and shows a potent antiviral activity against herpes simplex virus type-1, vesicular stomatitis virus, and coronavirus A-59. The complete determination of the structure was carried out during the total synthesis of onnamide A (43)... 

To study the antiviral activity, Type 1 simplex herpes virus, KOS stock (HSV-Hg) and Indiana vesicular stomatitis virus (VSV) were used and HeLa cells were cultured in Eagle-modified Dulbecco medium (EMDM), supplemented w ith 10% foetal calf serum, on plates with 24 holes. Monolayers of these cells were infected with HSV-1 or VSV at 0.5 ufp/cell or 0.01 ufp/cell, respectively, and later the product to be assayed, pre-dissolved in DMSO, was added in concentrations of 10, 20, 50, 100 and 200 pg/ml. After 48 h incubation for HSV-1 and 24 h for VSV, at 37°C in CO2 atmosphere, the cytopathic CPE effect was measured on a phase-contrasting microscope [85],... 

Evidence of antiviral effects has especially been shown for St. John s Wort [2,3,10], Plant preparations with different chemical composition have been assayed against various viruses and both, hypericin and pseudohypericin, were found to be particularly effective as virucidal agents. The two compounds have been shown to be active against a broad range of viruses and retroviruses, such as herpes simplex virus types I and II, vesicular stomatitis and influenza viruses, cytomegalovyrus and human immunodeficiency virus-1 [2,3,10,91,92]. 

Type I (IFN-a/P) and type II (IFN-y) IFNs are major lines of defense against viral infection. IFNs mediate direct antiviral effector mechanisms that inhibit multiple steps of viral replication (Samuel 1991 Vilcek and Sen 1996). For example, 2, 5 -oligoadenylate synthetase (2, 5 -OAS) activates ribonuclease L, which degrades mRNA and limits the accumulation of viral transcripts. Protein kinase R blocks translation of viral transcripts by phosphorylating translation initiation factor eIF-2. Mx proteins block influenza, vesicular stomatitis virus, and herpes simplex virus replication by an unknown mechanism.
