The efficacy of L-tryptophan in the reduction of sleep disturbance and depressive state in alcoholic patients.

Alcoholic male inpatients (N = 76) served as subjects in this study which examined the effect of L-tryptophan on depressive state and sleep disturbance. All subjects were residents of a 6-week alcohol treatment program at a Veterans Administration Medical Center. Subjects' degree of depression (Zung's Depression Scale) and sleep satisfaction (Webb's Post-Sleep Inventory) were measured four times during the study, just prior to and following ingestion of a substance that was either 3 gms L-tryptophan or 3 gms of an identical-appearing placebo. Subjects in the L-tryptophan/placebo condition received the active substance for 4 days followed by the placebo with a 4-day washout period in between. A second group of subjects received the same regimen of reverse order and a third received placebos on both occasions. There were two additional control groups that received no substances. All subjects in the study reported decreased levels of depression due to nonspecific treatment effects. The subjects who took L-tryptophan in either sequence reported even lower levels of depression. Sleep disturbance was not affected by L-tryptophan since it was barely present when the study began. A phenomenon referred to as the interval effect is discussed and an alternative explanation for this effect is offered.

[The electrical discharge of Torpedo marmorata under normal conditions and during hypoxia and anoxia. I].

The electric discharge of Torpedo M. can be considered as an index of the metabolic activity of the electric lobe of C.N.S. In groups of 10 Torpedoes the electric charge was measured: the mechanical stimulus was obtained by the falling of different weights from a determinate height. The experiment was then repeated in conditions of hypoxia: a fall of the electric discharge values was observed. The experiment was also carried out considering the time: after 14 hours the condition of anoxia occurred.

[Effects of dihydrodinoreburnameninol on the electrical discharge of Torpedo marmorata under normal conditions and during hypoxia and anoxia. I].

The electric discharge of Torpedo M. can be considered as an index of the metabolic activity of the electric lobe of C.N.S. in groups of 10 torpedo the electric discharge was measured: the mechanical stimulus was obtained by the falling of different weights from a determinate height. Other 10 animals, to which the substance was administered, showed an increase of the electric discharge. The experiment was then repeated in conditions of hypoxia: a fall of the values of the electric discharge was observed. Finally the experiment was carried out considering the time: after 14 hours the condition of anoxia occurred.

[Protection furnished by dihydrodinoreburnameninol on the electrical activity of Torpedo marmorata kept in water polluted by copper. I].

Studies carried out on neurons of Torpedo M. showed that copper creates an action of cellular damage inducing the synthesis of free radicals. Two groups of Torpedo, one for the control and the other one treated with dihydrodinoreburnameninol, were kept in sea water containing CuCl2. Then the measurement of the electric discharge was made: it was observed a clear dicrease in the Torpedo kept in conditions of pollution from copper, while the administration of dihydrodinoreburnameninol showed a protective action on the damaging effects.

The amenorrhoea-galactorrhea syndrome: present diagnostic and therapeutic perspectives.

Recent progress in the field of radioimmunology, especially as regards prolactin (PRL) assay, as well as the use of new drugs have opened new perspectives for a better understanding of the "amenorrhoea-galactorrhea syndrome" both from the diagnostic and therapeutic points of view. This syndrome which formerly was considered infrequent, is now observed more and more often, perhaps as a result of the more widespread use of drugs such as phenothiazines, reserpine derivatives, alpha-methyldopa and tricyclic antidepressants, as well as owing to the large-scale use of estrogens and above all of estrogen-progestogen contraceptives. The problems of etiopathogenesis and management of the amenorrhea-galactorrhea syndrome are complicated by the fact that a variety of factors are responsible, as is shown also by the classical nosographic classification with the Forbes-Albright syndrome in the presence of a pituitary tumour, the Chiari-Frommel syndrome of amenorrhea-galactorrhea following pregnancy, and the Argonz-del Castillo-Ahumada syndrome in the absence of lither pregnancy or tumor.

[Treatment of ovariectomized patients with intramuscular and nasal-spray synthetic calcitonin].

The activity of different formulations of synthetic calcitonins on the prevention of bone loss was evaluated in young women after oophorectomy. In the 1st study patients were treated or with salmon calcitonin (CTs) intramuscularly (100 I.U. every second day; 10 patients) either with CTs nasal spray (100 I.U. daily; 10 patients). In the 2nd study patients received or CTs i.m. (100 I.U. every second day; 10 patients) either a synthetic analogue of eel calcitonin (eCT) given i.m. (80 I.U. every 2nd day; 10 patients). All calcitonins formulations were given for 9 months with oral calcium supplement (1 g daily). In the 1st study no significant changes of bone mineral content (BMC) was found at the end of the treatment in both groups. In the 2nd study a statistically significant decrease of BMC was observed in the group treated with eCT while non relevant changes were found in the CTs treated patients. Slight side effects were observed in some patients treated with calcitonin formulations given i.m. Since salmon calcitonin nasal spray was well tolerated and prevented bone loss after oophorectomy its use might be recommended in the treatment of postmenopausal osteoporosis.
