    Notes: Abstract. In the present investigation wound healing was studied clinically in 8 younger (mean age 33.5 years) and 8 older patients (mean age 48 years), who were surgically treated for the same amount of severe periodontitis. This implies that the patients in the younger age group represented individuals with a higher degree of susceptibility to periodontal disease than the patients in the older age group. After surgery all patients were subjected to a carefully controlled oral hygiene program. Patients were recalled weekly until 8 weeks post surgery and again after 15 weeks for a final examination. At every recall session oral hygiene measurements were carried out and the bleeding tendency of the pockets was determined after probing with a standardized pressure. Bleeding on the basis of mechanical trauma after probing was considered to be a clinical parameter for wound healing in a plaque free environment.Results indicate that the oral hygiene program resulted in equally low plaque scores in both age groups. However, in a period from 5–15 weeks after surgery younger patients showed significantly more bleeding pockets than older patients. Furthermore it was found in both groups that the more loss of attachment there was, the slower the rate of wound healing.It was concluded that the time span for wound healing is longer in patients who are more susceptible to periodontal disease, than in those who are less susceptible.

    Notes: ‘Grasslands Huia’ white clover (Trifolium repens L.), ‘Grasslands Maku’ lotus (Lotus pedunculatus Cav.) and suckling clover (T. dubium Sibth) were grown in a controlled environment at various levels of P supply. Dry weights and the concentration of inorganic-, lipid-, ester- and residual-P in trifoliate leaves were measured. Lotus grew better than white or suckling clover at low P. White clover and lotus responded steeply to increased P and had similar shoot dry weights at high P. Suckling clover had lower shoot weights than the other species at all P levels. The superior growth of lotus at low levels of p was probably due to better root growth and P uptake. Lotus had higher shoot P concentrations at low levels of P but lower concentrations than the others at high levels. White clover and suckling clover had similar shoot P concentrations at all levels of supply. In white and suckling clover total leaf P concentration rose with P supply. Of the P fractions, inorganic-and residual-P showed the largest rises in concentration. The increases in lipid- and ester-P were smaller. Increases in lotus leaf P were small, primarily because of the relatively small rises in inorganic- and residual-P. White clover is a vigorous species but requires high levels of P for best growth. Suckling clover has a relatively small response to improvements in P availability. The behaviour of the various P fractions is similar to that in white clover. Lotus grows well at low P but also shows rapid growth at high P supply. Whether efficiency is defined as the ability to extract P from the environment or to maintain low internal P concentration, lotus makes efficient use of P over the whole range of P supply.

    Notes: The purpose of the present investigation was to study the effect of standardization of probing spot and direction of probe insertion into the pocket in conjunction with a probing force of 0.75 N on the reproducibility of pocket depth measurements. Nine patients were selected on the basis of about 50 % loss of alveolar bone support. After initial treatment 137 interproximal pockets were measured twice by three different examiners, successively by means of a pressure probe with a constant probing force of 0.75 N and a Merritt-B probe. During the next two weeks the examiners were trained by means of a video program to use the probe on a standardized spot and in a standardized direction of insertion into the pocket. After this training, all measurements were repeated in the same order of investigation. During the first as well as the second examination, the first examiner also scored bleeding on probing using the pressure probe. Analyses of variance were carried out in order to test the reproducibility of pocket depth measurements both before and after training. Possible influences of the depth of the pocket and the bleeding tendency of a pocket were included in the analyses. The results indicated that only a training program together with a standardized probing force leads to reproducible interproxima! pocket depth measurements. However, further analyses revealed that only non-bleeding pockets gave reproducible measurements whereas bleeding pockets did not. If, in addition, pocket depth was included in the analyses, it was found that this factor has no influence on the reproducibility. It was concluded that bleeding of a pocket seems to be more important for the reproducibility of pocket depth measurements than the factor pocket depth.

    Notes: Summary In two parallel studies, bitches with mammary tumour received single intralesional injections of BCG (1 mg: 107 living bacteria) and Corybacterium parvum (109 killed bacteria) (53 bitches) or C. parvum alone (129 bitches) at the same dosage. Control groups received injections, following the same protocol, of 1 ml BCG suspension medium diluted in saline in the first study (51 bitches) or no injections at all (120 bitches in the second study). A block dissection, including mammary tumours, adjacent mammary glands, and regional lymph nodes, was performed 2 weeks later in all animals. On the basis of histologically confirmed malignant tumours, 48 bitches (25 treated by immunotherapy and 23 controls) in the first study and 67 bitches (30 treated by immunotherapy and 37 controls) in the second study remained for postsurgical follow-up. The clinical tolerance of the treatment was generally good. No significant differences were found in cumulative survival rates between treated and control group in either studies.
