Xerotic skin appears dry, rough and slightly scaling. Patients complain of pruritus and stinging. Our aim was to investigate the clinical effects of a cosmetic ointment (Scherilan) in patients with circumscribed senile xerosis (also called asteatotic eczema). Moreover, variations in expression of epidermal proteins such as keratin (K)-5 and involucrin, detected by immunohistochemistry, were also evaluated before and after topical treatment. We enrolled 30 patients (11 males, 19 females) with asteatotic eczema. We examined dryness, roughness and desquamation and symptoms such as itching and dryness. A score of 0 to 3 was assigned to each of these parameters. A biopsy was performed in seven patients before and after a 21-day topical treatment. All skin specimens were then immunostained with antibodies to K5 and involucrin. At day 7 or 21 of treatment all signs of xerosis and pruritus were significantly reduced; furthermore, the reduction increased with the duration of therapy. Before treatment K5 was strongly expressed in stratum basale (SB) and stratum spinosum (SS), while involucrin was strongly expressed in stratum granulosum (SG) and the upper portion of SS. In contrast, after treatment immunostaining for K5 was restricted to SB and the lower part of SS, while involucrin showed intense staining in SG. We highlight the importance of treating cutaneous xerosis with an ointment such as this one, which probably induces an increase of lipid content of the SC intercellular matrix.","PeriodicalId":14404,"journal":{"name":"International journal of tissue reactions","volume":"27 1","pages":"23-9"},"PeriodicalIF":0.0,"publicationDate":"2005-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"25244162","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Regarding the hypothesis that the structure of the spleen lends it the function of a blood filter the substances described in our study might play a significant role in the functional morphology. Of 146 human spleen surgical specimens, groups of 12 specimens each were examined under a light microscope using the method of antibodies against fibronectin, against collagen types I-IV and against chondroitin sulphates A, B, and C. The sections of the red pulp of human spleen stained with hematoxylin and eosin provided limited information about the wall of the sinuses. Chondroitin sulphates A and B were observed on the surface of sinus-lining cells (SLC), and fibronectin was detected on the surface of the annular fibers. Collagen type 11 was observed almost in the same places as chondroitin sulphates A and B. Collagen type IV was present in annular fibers of the wall of the sinus and in the basement membrane, like fibronectin. Chondroitin sulphate was not present in the walls of sinuses. Binding of antibodies against chondroitin sulphate A and against chondroitin sulphate B indicates the presence of chondroitin sulfates on the surface of SLC, where they probably play a role in helping the human organism to recognize alien and self substances. The presence of chondroitin,sulphates A and B probably affects inhibition of binding of cells with collagen type I, but not with fibronectin.","PeriodicalId":14404,"journal":{"name":"International journal of tissue reactions","volume":"27 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2005-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"25244156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The control group consisted of 15 patients who had hypertension but no clinical osteoarthritis and did not receive any anti-inflammatory drugs. Twenty-four-hour ambulatory monitoring of BP and HR were performed on the day before initiation of rofecoxib therapy and on days 3 and 14 of COX-2 therapy. The control group underwent 24-h monitoring three times at similar intervals. Antihypertensive medications were continued. On day 3 of rofecoxib therapy, mean HR for both daytime and nighttime were lower than those at baseline. On day 14, the changes in mean HR did not differ from baseline values. Similarly, diastolic BP (daytime and nighttime) on day 3 appeared to be lower than at baseline. However this difference was not observed on day 14, and mean daytime and nighttime diastolic BP returned to baseline values. There was no statistically significant difference in the mean arterial pressure or systolic BP recordings on days 3 or 14 than at baseline.

Data strongly suggest that, because of its antioxidant properties, ALA is particularly suited to the prevention and/or treatment of diabetic complications that arise from overproduction of reactive oxygen and nitrogen. The aim of this study was to investigate the localization of nitric oxide synthetase (NOS) in normal and diabetic rat cavernous smooth muscles and to examine the effects of ALA on them. Rats were divided into four groups: control, diabetic, diabetic plus ALA, and ALA only. Penile tissues were taken 15 days after drug application and examined histochemically and immunohistochemically. Comparison of the control and diabetic groups revealed that the axons of nerve cells were not identified with Masson trichrome in the diabetic group, whereas in the control group NOS localization and immunostaining (endothelial NOS [eNOS]) were normal. Diabetic rats administered ALA showed improvement in Masson trichrome, nicotinamide adenine dinucleotide phosphate diaphorase (NADPH-d) and eNOS localization compared with untreated diabetic rats. Although there was no difference between the control group and the group administered ALA only, we observed an increase in NADPH-d and eNOS. In erection, eNOS and neuronal NOS (nNOS) may have a significant role. In pathologic conditions, erectile dysfunction may occur as a result of an increase in inducible macrophage-type NOS (iNOS). ALA plays an important role in treatment of erectile dysfunction by decreasing iNOS and increasing other isoforms of NOS.","PeriodicalId":14404,"journal":{"name":"International journal of tissue reactions","volume":"27 3","pages":"145-50"},"PeriodicalIF":0.0,"publicationDate":"2005-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"25765695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A dermal equivalent was first made in a petri dish by combining skin fibroblasts with collagen type I. Then a punch biopsy as a source of epidermal cells was implanted on this dermal equivalent, where a multilayered epidermis developed. The spray containing Rhealba oat extract was added to the culture medium to evaluate epidermal growth by immunohistochemical analysis of mitotic activity (5-bromo-2'-deoxyuridine [BrDu] incorporation). The extension of the neoepithelium in comparison with untreated reconstituted skin over 22 days was evaluated histologically. On day 12, 16% of positive BrDu basal cells was detected after spray treatment in comparison with 4.2% positive cells in untreated reconstituted skin (p < 0.05). During epidermal differentiation between days 12 and 22, we observed a significant increase in the number of cellular epithelial layers after 16 and 18 days of spray treatment. Moreover the extension of re-epithelialization was also significantly increased after spray treatment on days 16 and 18. In conclusion, our results demonstrate a positive modulation of re-epithelialization on a newly formed epithelium by a spray containing Rhealba oat extract displaying a healing effect.","PeriodicalId":14404,"journal":{"name":"International journal of tissue reactions","volume":"27 3","pages":"83-9"},"PeriodicalIF":0.0,"publicationDate":"2005-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"25765792","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
