Toxoplasmosis among cases of chronic tonsillitis.

One hundred cases aged 4-20 years and suffering from chronic tonsillitis were examined for Toxoplasma antibodies using indirect immunofluorescent test (IFAT). It was found that 37% of them were positive for toxoplasmosis. 41.5% of hypertrophic cases and 32% of atrophic ones had toxoplasmosis but the difference was statistically insignificant. The mean antibody titres were higher in both atrophic and hypertrophic cases than in the control group. The patients aged from 11-20 years had a higher titre of Toxoplasma antibodies than those aged below ten years. Trials to detect tachyzoites, cysts or pseudocysts in fixed paraffin sections using Hx & E, PAS or Giemsa stains were not successful. The histopathological picture of tonsils removed from positive cases of toxoplasmosis showed characteristics of toxoplasmic lymphadenitis.

[Phase changes in the population of group A streptococci and their influence on the course of the epidemic process of tonsillitis].

This work presents the data on the complex evaluation of the population of group A streptococci, studied at each of four phases (reservation, epidemic transformation, epidemic spread, reservational transformation) of the course of the epidemic process of streptococcal infection of the respiratory tracts (tonsillitis) in an organized group of adults. The characterization of the phases of the infective agent in accordance with the level of the carrier state, the size of streptococcal foci and the virulence of streptococci is given. Thus, the study shows that the heterogeneity of group A streptococci with respect to their virulence reaches its maximum level at the phases of reservation and epidemic spread and its minimum level at the phases of epidemic and reservational transformation. The size of streptococcal foci in carriers and the virulence of streptococci isolated from them are the inter-related unidirectional signs of the population of the infective agent and, at the same time, the main factors responsible for the phase character of the epidemic process and the morbidity level in tonsillitis.

Concentrations of flurithromycin in serum and tonsils.

The concentrations of flurithromycin in serum and palatine tonsils of eleven adult male patients undergoing tonsillectomy were determined. Each patient received 500 mg t.i.d., in all ten doses, before tonsillectomy. Flurithromycin concentrations were measured by a microbiological method. Mean serum levels (+/- SE) were 0.72 microgram/ml (+/- 0.19) after 8 h from the 9th dose and 0.67 microgram/ml (+/- 0.13) after 4 h from the 10th dose. Average concentrations (+/- SE) in tonsils were: 1.43 +/- 0.20 microgram/g (right) and 1.32 +/- 0.21 (left) 4 h after the last administration. Therefore, the mean tissue/serum ratio was about 2:1. These results indicate a good diffusion of flurithromycin from serum to tonsillar tissue.

[Bicycle ergometry in the diagnosis of cardiac lesions in chronic tonsillitis].

Bicycle exercise test, load myocardial 99mTc pyrophosphate (99mTc-PYP) scintigraphy and echocardiography were performed in 42 women with chronic tonsillitis between the ages of 18 and 35 years. Of the 21 patients with chronic decompensated tonsillitis combined with ventricular extrasystole and horizontal ST segment depression during the exercise test 18 exhibited diffuse myocardial 99mTc-PYP uptake. Patients with positive scintigraphic findings had reduced index of left-atrium emptying compared with controls and patients with a negative 99mTc-PYP test finding.

Co-operation between T and B lymphocytes from human tonsils in the response to mitogens and antigens.

Purified B lymphocytes obtained from human tonsil cell populations by removing E rosette-forming cells by density sedimentation did not proliferate at three days in response to PHA and Con A, but showed a significant 3H-labelled thymidine incorporation when the PHA response was assessed at day 6 of culture. The 6th-day responses, which was completely abolished by the reduction of T-cell contamination to less than 0-1% by re-rosetting and a second separation, was due in part to a direct activation by PHA of contaminating T cells and in part to a T cell-mediated B-cell response. When purified B cells were stimulated for 3 days by PHA in the presence of an equal number of autologous or homologous mitomycin-treated T lymphocytes a highly significant uptake of 3H-labelled thymidine was demonstrated. The majority of blast cells obtained at day 4 in these cultures were unable to form E rosettes and showed surface immunoglobulin by immunofluorescence stain. This response was markedly decreased by previous treatment of B cells with mitomycin C and it was abolished when B cells were killed by heating at 56degrees C for 1 hr. Purified B lymphocytes from human tonsils did not respond in vitro when cultured for 6 days in the presence of soluble antigens (PPD and Candida). However, a highly significant response to the same antigens could be demonstrated when B cells were cultured in the presence of autologous mitomycin-treated T cells. These models of T-B co-operation could provide an interesting tool for studying the differentiation and antibody production in vitro of human B lymphocytes.

Enzyme differentiation of lymphocyte subpopulations in sections of human lymph nodes, tonsils and periodontal disease.

Five enzymes have been studied to differentiate between T and B lymphocytes in sections of human lymph nodes, tonsils and chronic inflammatory periodontal disease. The presence of acid phosphatase, beta-glucuronidase N-acetyl-beta-glucosaminidase, non-specific esterase and fluoride-resistant esterase activity was determined histochemically. The results indicate that cells in the B area of both lymph nodes and tonsils are negative for enzyme activity, while those in the T area show a single intense granule of activity. These enzymes were unable to differentiate between T blasts, B blasts and plasma cells in the sections studied. The majority of the lymphoid cells in the lesions of chronic inflammatory periodontal disease are enzyme-negative and probably of B-cell origin.

Isolation of follicular dendritic cells from human tonsils and adenoids. VI. Analysis of prostaglandin secretion.

Follicular dendritic cells (FDC) are able to fix high amounts of immune complexes by C3b or Fc receptors without endocytosis and for long periods of time. In order to determine the function of this retention, we analysed the secretion of prostaglandin E2 (PGE2) by FDC in vitro; indeed, it is well-known that immune complex fixation on cells may induce PGE2 production. FDC were isolated by enzymic digestion of lymph follicles dissected under the biomicroscope from human tonsils or adenoids. Isolated FDC appeared as spherical clusters where they enveloped lymphoid cells with their cytoplasmic extensions. Tests were performed in synthetic culture media or in media supplemented with foetal calf serum. PGE2 production in FDC suspensions was compared to that of lymphocyte or macrophage-enriched populations prepared from the same human tonsils. In all experimental conditions, FDC and macrophage-enriched cell populations produced high levels of PGE2, inversely to lymphoid cell populations. This secretion was inhibited by indomethacin. At the ultrastructural level, we also showed that 3H-arachidonic acid was metabolized in cell membranes of all three cell types. The PGE2 produced in the culture media, according to our experimental conditions, do not influence cell proliferation, as assessed by 3H-thymidine incorporation tests on phytohaemagglutinin-stimulated lymphocytes.

[Lymphocyte sub-populations and immunoglobulin concentrations in palatine and fancial tonsils (author's transl)].

The number of B- and T-lymphocytes as well as the cytological composition and concentrations of IgG, IgM, and IgA are compared in children's palatine and fancial tonsils. The B-lymphocytes prevail in both organs. IgG is the main immunoglobulin and IgM and IgA follow in their concentrations. No significant differences between palatine and fancial tonsils were detectable at all investigated parameters. Evidence as to the biological equivalence of the organs is disclosed.

The tonsils are superior to the peripheral blood as sources of mononuclear cells for B-cell purification.

Various methods for B-cell purification from mononuclear cells of the peripheral blood and tonsils were evaluated. L-leucine methyl ester was found to be the best method for monocyte depletion when B cells were isolated. Purification of B cells by negative selection methods from peripheral blood mononuclear cells (PBMCs) resulted in cell populations containing less than 40% B cells. This was partly due to significant increase in the relative number of large granular lymphocytes during the purification procedures. However, when T cells and monocytes were depleted from tonsillar mononuclear cells (TMCs), 84.6% of the remaining cells were B cells. The cell populations isolated from PBMCs and TMCs by negative selection methods differed from each other also in their responsiveness to pokeweed mitogen. Positive selection methods, such as panning and cell sorting by flow cytometer, resulted in good purities with both PBMCs and TMCs. However, the cell yields with the positive selection methods were always very low. It is concluded that the tonsils should be favoured as sources of B cells when negative selection methods are used. When peripheral blood B cells are wanted, positive selection methods should be favoured.

[A parallel comparative double blind study of cefixime with cefroxadine in the treatment of acute lacunar tonsillitis].

The clinical efficacy and safety of cefixime (CFIX), a new oral cephalosporin, were compared with those of cefroxadine (CXD) in patients suffering from acute lacunar tonsillitis in a double blind study. Two hundred and fifty two patients were given each orally 100 mg of CFIX b.i.d. or 250 mg of CXD t.i.d. for, in principle, 7 days. Number of patients evaluated for clinical efficacy was 202 (103 treated with CFIX and 99 treated with CXD). As for the backgrounds of patients, more severe cases were found in the CFIX group than in the CXD group (P less than 0.01). Efficacy rates evaluated by individual doctors were 88.3% in the CFIX group and 91.9% in the CXD group. There was no significant difference between the 2 groups. Efficacy rates on the third day after the initiation of treatment evaluated by the committee were 40.8% in the CFIX group and 47.9% in the CXD group with no significant difference. Efficacy rate on the 7th day, however, was 79.8% in the CFIX group and 93.4% in the CXD group, showing a significant difference (P less than 0.05). Bacteriological effectiveness were satisfactory for both groups with eradication rates of 93.4% for the CFIX and 96.9% for the CXD group. Number of patients evaluated for safety was 226 (110 treated with CFIX and 116 treated with CXD). No significant difference was observed between the 2 drug groups in incidences of side effects; gastrointestinal disturbances or rashes were noted in 6 patients (5.5%) of the CFIX group and in 5 patients (4.3%) of the CXD group. As for the abnormal laboratory findings, elevation of GOT & GPT was observed in 1 patients of the CFIX group. From these results, it was concluded that 100 mg b.i.d. of CFIX was as useful as 250 mg t.i.d. of CXD in the treatment of acute lacunar tonsillitis.

[Sensitivity to an amoxicillin-clavulanic acid combination, of deep tonsillar flora isolated in chronic tonsillitis].

Deep tonsillar flora were identified in tonsils removed from 48 patients, children and adults, with chronic tonsillitis and recurrent sore throats or obstructive hypertrophy. Most specimens (38/48) cultured multiple germs (2 to 5 different species) with aerobic and anaerobic Gram+ and Gram-forms, some being beta-lactamase producers. Of the total of 135 strains isolated, 104 were aerobic and 31 anaerobic. The species of aerobic germs most frequently isolated were: Apart from alpha-hemolytic streptococci of undertermined group (38 strains), Haemophilus sp. : 14 (including 3 beta-lactamase + strains), Staphylococcus aureus: 15 (including 11 beta-lactamase + strains), Streptococcus A : 10, Enterobacteriaceae : 6, Neisseria sp. : 8 (including 1 beta-lactamase + strain). And among the anaerobic germs: Peptococcus : 3, Veillonella alc : 10, Fusobacterium nucleatum : 9, Bacteroides melaninogenicus : 6, Other Bacteroides : 2. Of the 127 strains tested, 102 were sensitive to amoxicillin and 121 to amoxicillin and clavulanic acid combination. The presence of a beta-lactamase producing bacterium in 1 of 3 specimens suggests the risk of failure of treatment with penicillin, prescribed classically for this type of affection.

Determination of cefatrizine levels in blood, tonsils, paranasal sinuses and middle ear.

Levels of cefatrizine, a new oral cephalosporin, were determined in blood and in tonsils, paranasal sinus secretions and middle ear exudates from 18 patients with acute infections at these sites. Three and six hours after administration of 500 mg cefatrizine satisfactory levels of the antibiotic were found at all the sites examined. Levels in the tonsils and middle ear were higher than those in blood, while lower levels were recorded in nasal secretions.

[Clinical evaluation of the TMS-19-Q.GC tablet in acute tonsillitis. A comparative double blind study with josamycin].

In order to compare the clinical efficacy and safety of TMS-19-Q.GC tablet (TMS) with josamycin tablet (JM) in acute tonsillitis, the double blind trial was carried out with the daily dosage of 200 mg X 3 in TMS and 400 mg X 3 in JM. Number of cases evaluated for clinical efficacy were 154 cases (73 treated with TMS and 81 treated with JM). The effective rating of TMS and JM were 89.0% and 88.9% judged by doctors in charge, and 82.2% and 85.2% judged by committee respectively. Bacteriological effects were satisfactory to yield the eradication rates of 93.8% in TMS and 94.7% in JM. Number of cases evaluated for safety were 199 cases (101 treated with TMS and 98 treated with JM). The incidence of side effect was 4.0% (4/101) in TMS and 5.1% (5/98) in JM and most of them were mild gastro-intestinal disorders. Number of cases evaluated for utility were 156 cases (74 treated with TMS and 82 treated with JM). The usefulness rates were 85.1% in TMS and 86.6% in JM. There was no significant difference between TMS and JM, in clinical effect, bacteriological effect, safety and utility. From these results, daily 600 mg dosage of TMS was as useful as daily 1,200 mg dosage of JM in the treatment for acute tonsillitis.

[Comparative study of different types of rosette-forming cells in human peripheral blood and tonsils].

E-, EA-, and EAC-reaction of rosette formation and detection of surface immunoglobulins were applied to the comparative study of the peripheral blood lymphocytes populations and tonsils in man. The relative lymphocyte content with different surface characteristics differed significantly in these populations. In detection of surface immunoglobulins on EAC-rosette forming cells it was revealed that not all the C3-lymphocytes of the tonsils bore surface Ig. A possibility of appearance of the C3-receptor on the activated T-lymphocytes is discussed.

[Tissue levels in human tonsils (tonsillae palatinae) following administration of different antibiotics (penicillin G, ampicillin, lincomycin)].

For determination of tissue levels of different antibiotics in human tonsils penicillin G, ampicillin or lincomycin is given i.v. to patients before tonsillectomy. The concentration of the individual substances is determined in tonsils and serum by agar diffusion method. The results are compared by diagrams of tissue and serum levels and statistically assessed. For therapeutic evaluation the absolute tissue levels at tonsillectomy are compared to the values of minimum inhibitory concentration (MIC) for most frequent germs in the stomato-maxillo-facial region. According to these results recommendations for antibiotic therapy of inflammatory processes of buccal cavity are given.

[Clinical evaluation of co-tetroxazine in acute purulent sinusitis and acute tonsillitis in a double-blind comparison].

127 outpatients, 78 with acute purulent sinusitis and 49 with acute tonsillitis, were treated for 7 days with a benzylpyrimidine -sulphonamide combination. In this double-blind and randomized study 59 patients received co- tetroxazine (100 mg tetroxoprim and 250 mg sulphadiazine) b.i.d., whilst the reference substance, co-trimoxazole (160 mg trimethoprim and 800 mg sulphamethoxazole) was given to the remaining 68 patients b.i.d. The test criteria were the therapeutic efficacy and both subjective and objective tolerance. An improvement in clinical symptoms and signs occurred in both conditions under each therapeutic regimen. Clinical therapeutic success was rated very good or good in 96.6% treated with co- tetroxazine and in 97.1% of patients treated with co-trimoxazole. In the former group therapy failed in 1 patient with sinusitis and in 1 with acute tonsillitis . In 98.3% of patients treated with co- tetroxazine the tolerance was very good or good, whilst the respective figure for co-trimoxazole was only 91.2%. 6 patients suffered from side effects ( gastric spasm, gastralgia , nausea, vomiting, diarrhoea) which were so severe in 2 cases that treatment had to be prematurely terminated. The generally good tolerance to both preparations was confirmed by the results of the laboratory investigations.

Ultrastructure of interdigitating cells in the human tonsil.

Electron microscopic investigations were performed on palatine tonsils from 12 patients with different disorders. In the tonsils a number of non-lymphatic cells were observed which showed the characteristic features of interdigitating cells (IDC): Interdigitating arrangement of the peripheral cytoplasm and invaginations of the cell membrane; Cells with typical tubulovesicular structure, and Partly an electron-lucent cytoplasm. A difference in functional phase may explain the ultrastructural feature of the IDCs. The nucleus, usually containing one or two nucleoli, is mostly multilobulated. These cells are frequently surrounded by mononuclear cells showing ultrastructural characteristics of T-lymphocytes.

[Microscopic anatomy of the palatine tonsils of adult humans].

Structure of the palatine tonsils has been studied in 77 mature, elderly and old persons (from 21 up to 90 years of age) who had no any diseases of the mouth cavity, nose and throat by the time of their death. Correlation of the lymphoid and connective tissue in the palatine tonsil parenchyma in the mature and old ages is not equal. Cross section area of the lymphoid tissue, lymphoid nodules including, beginning from the first mature age, is gradually decreasing, while the area occupied by the connective tissue is increasing. In persons of the elderly and old ages the number of the nodules with a light center and without it decreases. The area occupied with internodular lymphoid tissue reduces.
