Cutaneous lesions of the human sexually transmitted genital ulcer disease chancroid are characterized by the presence of intraepidermal pustules, keratinocyte cytopathology, and epidermal and dermal erosion. These lesions are replete with neutrophils, macrophages, and CD4(+) T cells and contain very low numbers of cells of Haemophilus ducreyi, the bacterial agent of chancroid. We examined lesio...

Synthetic peptides that correspond to the COOH-terminal portion of C2b enhance vascular permeability in human and guinea pig skin. In human studies, 1 nmol of the most active peptide of 25-amino acid residues produced substantial local edema. A pentapeptide and a heptapeptide corresponding to the COOH-terminal sequence of C2b each induced contraction of estrous rat uterus in the micromole range...

A 3-year-old entire male guinea pig (Cavia porcellus) was presented with a mass on the neck, which excised surgically. Histological examination and immunohistochemistry confirmed to be tumour of endothelial origin consistent an inflammatory lobular capillary haemangioma, despite some microscopic features triggering initial suspicion histological malignancy. Following surgical treatment, patient...

Tropical formulations of 5-trifluoromethyl-2'-deoxyuridine (TFT) containing different concentrations of TFT, Azone (Nelson Research and Development, Irvine, Calif.), and propylene glycol were evaluated for their potential efficacy in the treatment of cutaneous herpes simplex virus infections by in vitro studies of TFT penetration through skin and in vivo studies of therapeutic activity against ...

Delayed hypersensitivity in guinea pigs was produced by immunization. with a conjugate prepared by coupling diazotized arsanilic acid to polytyrosine. The resulting sensitivity could be demonstrated by skin test with conjugates prepared from a wide variety of tyrosine-containing proteins. Definite but smaller degrees of sensitivity could be induced with conjugates of proteins containing little ...

Taenia solium is a zoonosis found all over the world, especially in developing countries. T can cause taeniasis and cysticercosis humans. Pigs as intermediate hosts be infected with which causes porcine cysticercosis. infect muscle, skin, eye, brain tissue develop into neurocysticercosis. Neurocysticercosis of 30% cases epilepsy world. In Denpasar city, pigs are one type livestock. A large numb...

Cystic changes of ovarian tissue are crucial as they cause infertility in laboratory animals. A 4 years old, weighing approximately 500 g adult, intact guinea pig had pruritic progressive alopecia over the flanks at dorsal area and abdomen symmetrically, bilaterally for a month. Beside, an abdominal enlargement was observed outside on pig. Large polycystic ovaries were detected behind kidneys d...

Purpose: Miconazole nitrate is a widely used antifungal agent but its use in topical formulation is not efficacious because deep ereated fungal infections are difficult to treat with conventional topical formulation. The purpose of this study was to prepare miconazole incorporated different novel carriers such as liposomes, ethosomes and to compare their in vitro skin permeation studies with pl...

This study is focused on in vitro permeation of the original Czech compound, a skin/mucosa tissue regeneration promoter, known under the international nonproprietary name "alaptide," in micronized and nanonized forms. Alaptide showed a great potential for local applications for treatment and/or regeneration of the injured skin. The above mentioned technological modifications influence the perme...

Controlled-release delivery of 6-beta-naltrexol (NTXOL), the major active metabolite of naltrexone, via a transdermal patch is desirable for treatment of alcoholism. Unfortunately, NTXOL does not diffuse across skin at a therapeutic rate. Therefore, the focus of this study was to evaluate microneedle (MN) skin permeation enhancement of NTXOL's hydrochloride salt in hairless guinea pigs. Specifi...
