Endocrine profile and seminal plasma composition in 45 patients with tuberculoid-type Hansen's disease are reported. There was marked reduction in sperm count and motility (p less than 0.01, p less than 0.01, respectively) with an increase in abnormal forms of spermatozoa (p less than 0.05). The levels of serum prolactin and oestradiol-17B were increased significantly (p less than 0.05, p less than 0.05, respectively) with a marked reduction in serum FSH, LH and testosterone (p less than 0.05, p less than 0.05, p less than 0.05, respectively). The possible significance of these findings may help further to understand male reproductive function in Hansen's disease.

An experimental examination of the lifetime limiting processes in a whole-heated sealed-off CuBr laser is performed. The influence of the CuBr expenditure, the pollution of the laser windows, the recombination processes and the change of the plasma composition, especially the bromine concentration increase is investigated. Considering the experimental results a sealed-off CuBr laser of not less than 500 h of operation is designed.

Heparin was shown to be a life-saving treatment in the otherwise lethal syndrome following intravenous injection of Ehrlich ascites tumour cells in cycloheximide-treated mice, and in mice treated with cycloheximide 2 h after injection of Ehrlich tumour cells. The effectiveness of heparin cannot be attributed to interference with initial arrest of tumour cells. A similar lethal syndrome, again prevented by heparin treatment, occurs in mice given intravenous colloidal carbon and cycloheximide. It is suggested that large doses of intravenous particulates bring about changes in plasma composition which are rapidly rectified in an otherwise normal mouse, but which persist under the influence of cycloheximide and lead to the irreversible and fatal outcome. Finally, evidence is presented which suggests that liver protein synthesis may play an essential role in the period following intravenous injection of tumour cells in an otherwise normal mouse.

Summary The plasma composition of cholesteryl ester fatty acids and levels of triglycerides and cholesterol were determined individually in 13 patients with coronary heart disease. Measurements were made before, during and after treatment with CPIB. In all patients CPIB decreased the proportion of cholesteryl linoleate and increased oleate and palmitoleate. Serum triglyceride levels were reduced in more patients and to a greater extent than cholesterol. The relationship of these findings to those in the recent literature are discussed.

SummaryTurkeys treated with diethylstilbestrol (DES) were fed various levels of iodinated casein (Protomone). Mortality was lowered and body weights were elevated by increasing amounts of Protomone in the feed of DES-treated poults. Systolic blood pressure and plasma composition of DES-treated poults fed a high level of Protomone, most nearly approximated the corresponding values for control birds, but did not attain the values for control poults. The histology of the thyroid glands of DES-treated turkeys was altered by the feeding of a high level of Protomone.

The mineral and organic composition of seminal plasma, physical spermatological parameters and their physiological relationships were investigated in Salmo trutta macrostigma. The seminal plasma contained 121.0 +/- 0.37mM/lI (Na+), 8.18 +/- 0.03mM/l (K), 7.23 +/- 0.03 mg/dl (Ca2+), 3.19 +/- 0.02 mEq/l (Mg++), 0.48 +/- 0.02 g/dl total protein, 6.07 +/- 0.06 mg/dl cholesterol, 6.24 +/- 0.08 mg/dl triglyceride and 9.97 +/- 0.39 mg/dl urea. The following physical spermatological parameters were found out: sperm volume 13.93 +/- 0.84 ml, sperm motility 80.37 +/- 2.36%, movement duration 81.47 +/- 4.21 s, density 6.02 +/- 0.46 x 10(9)/ml, total density 8.85 +/- 6.12 x 10(9) and pH 7.53 +/- 0.20. Significant positive relationships were determined between motility duration and motility (r = 0.83, P < 0.01) and also between spermatocrit and motility (r = 0.536, P < 0.05). Sperm volume and total density negatively correlated with motility (r = -0.191, P > 0.05 and r = -0.087, P > 0.05, respectively). The Na+, K+ and Cl- ions correlated negatively with motility (r = -0.267, P > 0.05, r = -0.152, P > 0.05 and r = -0.461, P > 0.05, respectively). On the other hand, the Ca2+ and Mg2+ ions correlated positively with motility (r = 0.114, P > 0.05 and r = 0.040, P > 0.05, respectively). A significant negative relationship was found between motility and urea (r = -0.515, P < 0.05). These parameters should be considered when developing procedures for short-term storage or cryopreservation of the Salmo trutta macrostigma sperm.

We report measured Stark widths and shifts of the neutral argon 425.9 nm line. A wall stabilized arc is used as a plasma source. Electron densities of 0.5 − 3.5 × 1022 m−3 are determined from the width of the Hβ line and electron temperatures of 9000-11,000 K are deduced from plasma composition data. Measured Stark widths and shifts are systematically smaller than semi-classical theoretical results. Comparison of the experimental Stark widths and shifts with theoretical data shows gradual increase of the discrepancy with temperature. This is more distinctive in the case of shifts.

The usual technique of the laser induced plasma spectroscopy (LIPS) spectra analysis relies on the use of calibration curves for quantitative measurements of plasma composition. However, LIPS calibration curves strongly depend on the material composition (the so-called matrix effect); thus, this standard approach to the LIPS spectra analysis is inadequate when precise information on unknown samples composition is required. In this paper we present a new procedure, based on LIPS, for calibration-free quantitative elemental analysis of materials. The new procedure, based on an algorithm developed and patented by IFAM-CNR, allows the overcoming of the matrix effect, yielding precise and accurate quantitative results without the need of calibration curves.

It has been shown that monitoring the radio-frequency reflected power in plasma etching provides a simple and very inexpensive tool for end-point detection. The technique, based on the change in plasma impedance associated with the change in plasma composition, has been successfully applied to polysilicon and silicon and nitride etching.

A method is described for varying the electron temperature of a plasma (target-plasma) in a double plasma device from 0.05 to 1.3 eV by adjusting the thermionic emission of electrons from filaments used in the region.

Neoclassical transport coefficients are derived for a multi‐species plasma in a mixed regime, with several banana‐plateau species, a, and several Pfirsch–Schluter species, z. It is assumed that ma≪mz, but the masses are otherwise arbitrary.

The first section outlines a problem-oriented approach for evaluating children with renal diseases as they might present in a general pediatric practice. Hypertension, azotemia, hematuria, proteinuria, short stature, and polyuria are discussed, from the viewpoint of history and physical examination and laboratory data, emphasizing the differential diagnostic points of specific disease entities. This section will be most valuable to house officers and general pediatricians. The tables, figures, and line diagrams are informative and complete. The chapter on abnormalities of plasma composition is exceptionally well outlined and complete. A companion chapter on the treatment of these abnormalities would have been welcomed. The middle section discusses the management of the more common pediatric nephrological problems. The chapters reviewing the management of renal failure are particularly informative and comprehensive. The pathophysiology of renal insufficiency and therapy based on these concepts are clearly discussed. This is a timely subject, especially for general pediatricians, since
