Reproductive endocrine effects of intranasal administration of norethisterone (NET) to women.

Four consecutive menstrual cycles were studied in six healthy parous women. A solvent mixture comprising propylene glycol:ethanol:water (3:3:4) was sprayed intranasally daily using a glass atomizer between days 5 and 24 of the first (control) menstrual cycle. NET was dissolved in the solvent and similarly administered at a daily dose of 100 mcg during the second and third menstrual cycles. Nasal sprays were not administered during the fourth post-treatment cycle. Blood samples were taken during four consecutive cycles between days 8 and 15 and again between days 20 and 24 of the cycle to estimate levels of estradiol (E2), FSH, LH and progesterone (P). These studies revealed that nasal sprays of NET were well accepted and that no adverse clinical effects or menstrual disturbances occurred. NET inhibited ovulation in one cycle. The E2-induced mid-cycle rise in FSH and LH was either suppressed or inhibited in nine out of the 12 treated cycles. P levels in three treated cycles were indicative of luteal inadequacy. These endocrine effects of NET persisted into the post-treatment cycle in two cases.

Quantitative electromyography using automatic analysis. A comparative study with a fixed fraction of a subject's maximum effort and two levels of thresholds for analysis.

Quantitative electromyographic (QEMG) data recorded with two levels of threshold for the apparatus are compared. Using a fixed fraction of a subject's maximum effort the data are shown to be independent of sex, age and the strength of the muscles. The diagnostic yield of such a method is shown to be better with 50 muV threshold for analysis than with 100 muV, in cases of muscle disorders such as Duchenne muscular dystrophy and polymyositis. However, in cases of neurogenic lesions due to anterior horn cell disease the diagnostic yield remains the same with both thresholds.

Muscle transketolase in normal foetuses and Duchenne dystrophy.

The activity of the enzyme transketolase (EC 2.2.1.1) or the pentose phosphate metabolizing enzyme (PPME) was investigated in the quadriceps muscles of patients with Duchenne muscular dystrophy (DMD), polymyositis and spinal muscular atrophy (SMA) and in normal foetuses. The enzyme activity was significantly elevated in these muscle disorders with highest and lowest levels seen in DMD and SMA groups, respectively. The enzyme activity was increased early in DMD muscle and appeared to increase with progression of the disease. Normal foetal muscle contained high transketolase activity which is comparable to that seen in DMD patients.
