And Control

Root systems of young and mature lodgepole pine (Pinus contorta Dougl. var. latifolia Englem.) were removed from forest stands and the associated aerobic bacterial flora isolated. Characterization of rhizoplane and control soil isolates from these tree root systems demonstrated differences from that reported for agricultural crops. Ammonifying, proteolytic, and amylolytic organisms were proportionately reduced within the rhizoplane. The rhizoplane organisms grew more slowly than the control soil isolates, although they responded in greater numbers to the addition of an amino acid supplement to the growth media. The rhizoplane organisms also showed an increased ability to solubilize phosphate. The chitinolytic organisms were suppressed within the rhizoplane of the mature tree but were stimulated by the young trees. With this exception, the rhizoplane microflora of older and younger trees were similar.

A serious outbreak of staphylococcal infections in the maternity units in Blackburn was investigated. There were considerably more than one hundred cases of breast abscesses altogether, well over half of which occurred in primiparae. Staphylococcus aureus, phage type 80, was the predominating organism throughout the outbreak and at the peak period during the early part of the outbreak this type was responsible for nearly 80% of the infections.After the introduction of a number of procedures for the general reduction of cross-infection the incidence of breast abscess fell markedly and a controlled trial of an antibacterial cream, containing neomycin and hibitane, which was applied to the nasal mucosa of all infants and mothers in the test group of patients, was undertaken. The conditions obtaining in the test and control groups were identical in every way except that the control patients did not receive the neomycin-hibitane cream. There were about 1250 mothers and infants each in the test and control groups; the incidence of breast abscesses in the test group was 0·8% and in the control group it was 2·7%. The method adopted for the detection and treatment of carriers among the nursing staff broke down on two occasions; this fact and the emergence of an unforeseen source resulted in a larger number of infections than should have occurred. Had it not been for these incidents there is little doubt that the trial would have shown more conclusively the effectiveness of the neomycinhibitane cream, by the method laid down, in reducing cross-infection.Investigation of the bacterial flora on the nasal mucosa of over 1000 infants in the control group yielded results of considerable interest. Of 300 cases where there was early colonization by Staph. albus, this organism established its dominating position in 70% of the cases and it was not subsequently displaced by Staph. aureus. The significance of this observation and the evidence favouring nasal dissemination of Staph.aureus as the most important cause of hospital cross-infection are discussed.

Changes in poultry processing and marketing over the past few decades have resulted in production of many convenience food items. These products are subjected to much handling and require that strict attention be given to sanitation measures. Many types of microorganisms are present on poultry products as a result of contamination from feathers, feet, and intestinal contents of the birds. Equipment and personnel on processing lines also contribute to the spread of bacteria. The bacterial flora may be significant in causing spoilage, or may represent a public health hazard unless controlled by proper sanitation and cooking or low temperature, Trends in bacterial numbers during processing vary with different plant practices and the adequacy of plant sanitation; examples of these differences are described. Several investigations are reviewed on microorganisms present on poultry from the farm through the finished product, including retail store practices. Sources and control of salmonellae and other potential pathogens are discussed.

The aim: To study the effectiveness of chronic apical periodontitis treatment by the combined use of ultrasonic treatment of root canals and multicomponent antimicrobial gel according to the results of clinical and microbiological researches. Materials and methods: 64 patients with chronic apical periodontitis at the age of 18-56 years were treated. Patients were divided into two groups: the main and control. In the main group the root canals of 36 teeth were sonicated in combination with multicomponent antimicrobial gel, in the control – 35 teeth were treated by a standard method. The content of the root canals for microbiological studies was obtained before endodontic treatment and before permanent obturation. Frequency of content and number of bacteria in the samples were evaluated. Results: All samples before treatment were positive for the presence of variable bacterial flora, among which Staphylococcus epidermidis (43.9%), Enterococcus faecalis (37.9%), Streptococcus spp. (24.8%), Candida albicans (24.4%), Fusibacterium (9.4%) were the most dominant, their number was 7.4-4.8 lg CFU/ml. Repeated research after the proposed and standard method of root canal decontamination has shown a significant decrease in microflora. According to the data of clinical and microbiological examination, the method which was developed by us revealed a positive result in 86% of cases compared with 63% when treated by the standard method. Conclusions: The effectiveness of a complex treatment method with combined use of the ultrasonic irrigation and multicomponent antimicrobial gel for root canals decontamination in chronic apical periodontitis is demonstrated. Significant reduction of microflora growth and destruction of microbial associations, good penetration of multicomponent antimicrobial gel into endodontic structures due to ultrasound compared with a standard method were achieved.

Electric fields have been applied across oxides growing on a high temperature alloy and control of the oxidation of the material has been demonstrated. At present, three-fold increases in the oxidation rate have been measured in accelerating fields and the oxidation process has been completely stopped in a retarding field.The experiments have been conducted with an iron-base alloy, Pe 25Cr 5A1 0.1Y, although, in principle, any alloy capable of forming an adherent aluminum oxide layer during oxidation can be used. A specimen is polished and oxidized to produce a thin, uniform insulating layer on one surface. Three platinum electrodes are sputtered on the oxide surface and the specimen is reoxidized.

The majority of blood vessels in the superior cervical ganglion possess a continuous endothelium with tight junctions. These same features have been associated with the blood brain barrier of the central nervous system and peripheral nerves. These vessels may perform a barrier function between the capillary circulation and the superior cervical ganglion. The permeability of the blood vessels in the superior cervical ganglion of the rat was tested by intravenous injection of horseradish peroxidase (HRP). Three experimental groups of four animals each were given intravenous HRP (Sigma Type II) in a dosage of.08 to.15 mg/gm body weight in.5 ml of.85% saline. The animals were sacrificed at five, ten or 15 minutes following administration of the tracer. Superior cervical ganglia were quickly removed and fixed by immersion in 2.5% glutaraldehyde in Sorenson's.1M phosphate buffer, pH 7.4. Three control animals received,5ml of saline without HRP. These were sacrificed on the same time schedule. Tissues from experimental and control animals were reacted for peroxidase activity and then processed for routine transmission electron microscopy.

It is well known that the rat adrenal zona glomerulosa steroidogenic activity is controlled by the renin-angiotensin system. The ultrastructural changes in the rat zona glomerulosa cells induced by renovascular hypertension were described previously, but as far as we are aware no correlated biochemical and morphometric investigations were performed.Twenty adult male albino rats were divided into 2 experimental groups. One group was subjected to restriction of blood flow to the left kidney by the application of a silver clip about the left renal artery. The other group was sham-operated and served as a control. Renovascular hypertension developed in about 10 days: sistolic blood pressure averaged 165 ± 6. 4 mmHg, whereas it was about 110 ± 3. 8 mmHg in the control animals. The hypertensive and control rats were sacrificed 20 days after the operation. The blood was collected and plasma renin activity was determined by radioimmunological methods. The aldosterone concentration was radioimmunologically assayed both in the plasma and in the homogenate of the left capsular adrenal gland.
