Although Dae-Bang-Poong-Tang (an herbal formula of 15 herbs)-treated rats exhibited a mild inflammation, the significant histological changes including a marked infiltration of inflammatory cells in the synovium and damaged articular cartilages were not observed. The staining abilities of the cartilage such as periodic acid Schiff's reaction in the interterritorial matrix of hyaline cartilage, alcian blue and aldehyde fuchsin staining in the capsule of chondrocytes and in the interterritorial matrix of articular cartilage and Con A, sWGA and BSL-1 affinities of chondrocytes tended to decrease in the rats with collagent-induced arthritis compared with normal rats. Decreased stainabilities and affinities were almost recovered in the Dae-Bang-Poong-Tang-treated rats. In the collagen-induced rats, iNOS expression in the synovial lining cells and subsynovial tissue were significantly increased and numerous strong immunoreactive cells were demostrated in the subsynovial tissue. Somewhat decreased immunoreaction of iNOS was shown in the synovial lining cells and subsynovial tissue of Dae-Bang-Poong-Tang-treated rats. It was concluded that Dae-Bang-Poong-Tang showed a notable protection against histological changes and histochemical staining, and it acted as an inhibitor of iNOS expression. Dae-Bang-Poong-Tang may be used as a complementary therapeutic agent to alleviate the rheumatoid arthritis.

NF-κB plays a pivotal role in pathogenesis in general arthritis. However, the participation of NF-κB in inflammation of the temporomandibular joint (TMJ) is poorly understood. We examined NF-κB expression in rat TMJs with synovitis induced by condyle hypermobility. By immunohistochemistry, NF-κB immunoreactivity was found mainly in the cytoplasm, not the nucleus, of the synovial lining cells of induced-synovitis and control TMJs. Southwestern histochemistry, a new method for detecting transcription factors, showed greater NF-κB expression in the nucleus of the synovial lining cells in the hypertrophic synovium than in control synovium. Increased numbers of the synovial lining cells with immunoreactivity for inducible nitric oxide synthase (iNOS), which is transcriptionally regulated by NF-κB, were also seen in the inflamed synovium. These findings indicate that excess mechanical stress increases NF-κB activation in the TMJ and suggest that active NF-κB is involved in the progression of TMJ inflammation.

Luteinizing hormone (LH) was localized immunohistochemically to cells in the pars anterior and pars tuberalis of the human pituitary gland. Upon restaining with a variety of histochemical procedures, LH-containing cells were found to be aldehyde fuchsin and periodic acid-Schiff (PAS) positive; however, the intensity of histochemical staining failed to correlate with that of fluorescence. Only a few of the PAS- or aldehyde fuchsin-positive cells contained LH. In contrast to the above, with the performic acid-alcian blue-PAS-organge G sequence of Adams, all cells containing LH were turquoise colored, alcian blue-positive (S1 mucoid cells) and vice versa. This study was performed with antiserum specific for human chorionic gonadotropin which was shown to cross react in immunodiffusion analysis with purified human pituitary luteinizing hormone and to be capable of neutralizing its biological activity.

Correlated histochemical and autoradiographic studies were conducted on rat, rabbit, cat and dog salivary glands. Mucous acini of rat minor sublingual (SL) rabbit SL and cat posterior SL and submandibular (SM) glands were stained by Alcian Blue at pH 1.0, aldehyde fuchsin or the high iron diamine technique. The distribution of cells with this type of basophilia corresponded with that of cells shown autoradiographically to incorporate S35O4= and accordingly to contain sulfomucin. The lack of periodic acid-Schiff and alcohol-resistant metachromasia at pH 0.5 of rabbit SL mucin resembles connective tissue mucopolysaccharide. Some mucous acini of the dog posterior SL gland incorporate S35-sulfate and the distribution of isotope-labeled acini correlates with that of acini showing histochemical staining indicative of sulfomucin. The remainder of mucous acini in this gland do not show uptake of radiosulfate, but have alcianophilia that is reduced by sialidase digestion. All of the mucous acini of dog SM gland show correspondence of staining for sulfomucin with S35O4–, incorporation. The seromucous demilunes of this gland manifest sialidase-labile alcianophilia. The staining of sulfomucin and S35 labeling in each of the salivary glands studied are eliminated by a 4-hr methylation at 60°C.

The effects of treatment with a monoclonal antibody (R73 mAb) against T cell receptor alpha/beta (TCR-alpha/beta) on both established adjuvant arthritis (EAA) and established collagen-induced arthritis (ECIA) in rats have been investigated. Rats were treated with R73 mAb when arthritis reached a peak. Treatment with the anti-TCR-alpha/beta mAb markedly suppressed EAA, whereas ECIA was not affected by the mAb treatment. Histologically, R73 mAb-treated rats with EAA showed mild hyperplasia of synovial tissues, sparse infiltration of inflammatory cells, and minimal erosion of cartilage, whereas arthritic rats treated with PBS and an irrelevant control mAb against Giardia had marked hyperplasia of synovium with pannus, massive inflammatory cell infiltrate, and severe destruction of cartilage and subchondral bone. R73 mAb-treated rats with ECIA exhibited pronounced formation of pannus containing many inflammatory cells and marked cartilage and subchondral damage similar to those in arthritic rats that received the control treatments. Treatment with R73 mAb depleted markedly alpha/beta+ T cells in both peripheral blood and synovial tissues of rats with EAA and ECIA. R73 mAb treatment was associated with marked reduction in arthritogen-specific delayed-type hypersensitivity responses in both EAA and ECIA. The titers of antibodies against type II collagen produced in rats with ECIA were not affected by the mAb. Thus, alpha/beta+ T cells appear to have a central role in EAA, but not in chronic ECIA.

Mucosubstances (MS) were examined in 10½-14½-day embryonic rat hearts utilizing nonaqueous fixatives or formaldehyde vapor-fixed frozen sections hydrated in concentrated solutions of cetylpyridinium chloride. Ribonuclease-resistant, polyanionic sites were limited to the extracellular cardiac jelly, endocardium and fibroblastic cells (cushion tissue) associated with the endocardium. The cardiac jelly and endocardium of day 10½ embryos principally contained a hyaluronic acid-like carboxylated mucosubstance whose alcianophilia at pH 2.5 was abolished by hyaluronidase but was resistant to NaOH extraction and neuraminidase and trypsin digestion. A critical electrolyte concentration of 0.2 M MgCl2 abolished alcianophilia. On days 13½-14½ carboxylated MS were restricted to cushion tissue and partially resisted mild methylation. Sulfated MS were limited to primitive endocardial cells which gave origin to cushion tissue. Dye deposits of aldehyde fuchsin, high iron diamine or Alcian Blue (pH 1.0) were localized on cell surfaces and such staining was prevented by strong (60°C) methylation. Hyaluronidase sensitivity of sulfated MS decreased with gestation. The critical electrolyte concentration varied from 0.5-0.7 M MgCl2 on days 11½-12½ to 0.8-0.9 M MgCl2 after day 12½. The sulfated MS of endocardial cells were preceded by a transitory accumulation of diastase-resistant, periodic acid-Schiff-positive material. Possible roles of MS in normal and abnormal cardiac septation processes are discussed.

Background: Prophylactic extraction of the asymptomatic impacted third molar is routinely practiced in Europe and the United States. The justification for prophylactic extraction includes the need to reduce the risk of pathologic changes such as cysts and tumors.   Objectives: This study aimed to study the histological and radiological changes in the tooth follicles of upper and lower complete impacted 3rd molars -which appeared radiologically normal. Material and method: A prospective study included fifty patients aged 20 years and above who were referred to the Oral Surgery Clinic, Faculty of Dentistry, University of Sana'a. Patients had follicular space between (2.5mm -3mm) as measured by the panoramic X-ray. These teeth were removed surgically and the follicle was sent for histopathological examination. Results: Most histopathological changes were in dental follicles with a size of <2.5 mm (86%), and only 14% with 2.5 mm - 3 mm. There was statistical significance between the smallest size of dental follicles with the incidence of pathological histological changes indicating a high probability of developing neoplasm (p =0.008).  Of the 50 follicular patients, 28% showed HC, nine (64%) had ameloblastoma, four (29%) had a dentigerous cyst, and only one case (7%) had a multicalcified focus with islands of odontogenic epithelium. While 72% of the samples had normal follicles and non-specific chronic inflammatory cells. There is an association between female sex and pathological histological changes (12 females: 2 males, p =0.008), age group 21-25 years (93% HC), with mandibles (65% HC). Regarding angle and histopathological changes, 36% were vertical, 29% mesioangular, 14.2% horizontal and destioangular, and 7.1% buccoangular. Conclusion:  High incidence of HC occurred in patients with DF, and it was associated with smaller dental follicle size, most HC was ameloblastoma, followed by dentigerous cyst, while 72% of samples had normal follicles and non-specific chronic inflammatory cells. There is a correlation between female gender, younger age group, and jaw position with HC. Prophylactic extraction of the asymptomatic impacted third molar should be routinely practiced in Yemen, to reduce the risk of pathological changes, especially in females and younger age groups.                            Peer Review History: Received 11 January 2021; Revised 8 February; Accepted 28 February, Available online 15 March 2021 UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system.

&nbsp; The objective of this investigation was to study the histological and histochemical structure of the Harderian gland in native chickens. Samples were obtained from 10 male and 10 female adult healthy native chickens. Tissue sections were stained with haematoxylin eosin, Verhoeff&rsquo;s, Masson&rsquo;s trichrome, alcian blue (pH&nbsp;2.5), periodic acid-Schiff and Gomori&rsquo;s method for reticulum. The multilobular Harderian gland of native chickens was covered by a thin connective tissue which consisted of adipose tissue, parasympathetic ganglia, nerve bundles, collagen, elastic and reticular fibres. Plasma cells were present in interlobular areas. The Harderian gland was compound tubulo-alveolar type. The Harderian duct was lined by columnar epithelial cells of varying height. Goblet cells were not found in Harderian duct. Histochemical staining revealed that the all epithelial cells of both corpus glandulae and ducts contained both neutral and acidic mucins. No significant sex-based differences were found. It is concluded that the general histological and histochemical structure of the Harderian gland in native chickens is similar to that of domestic geese, but that there are also some differences. &nbsp;
