[Treatment of cutaneous losses of the heel with lateral calcaneus artery flap].

The lateral calcaneal artery flap is an axial flap which comprises also the saphenous vein and the sural nerve. Its use has been reported for coverage of skin loss of the malleolus and calcaneal area. The donor area should be closed by a split thickness skin graft.

[Treatment of complex nose deformities by external approach].

The authors present thirty patients with complex nasal deformities operated on by external approach. The incision was on the nasal columella. They used bone and cartilage grafts for the correction of the deformities.

[Treatment of losses of bone substance of the frontal region with outer table autogenic graft].

Ten patients with losses of frontal bone were operated with the use of bone grafts taken from the parietal area without craniotomy. In all patients the contour was restored without complications at the donor area. Results were evaluated clinically and radiologically one year later and no absorption was observed.

Splenic hydatidosis.

This report is concerned with ten patients treated surgically for a splenic hydatidosis. Splenic echinococcosis represents 3.5% of abdominal hydatid cysts treated in our Service.

[Autologous fat transplantation in rats].

The authors perform an experimental study in rats to demonstrate the integration of fat cells transplanted from the inguinal region to the dorsal region of the same animal. Histological studies were performed with the material removed and with the material injected. Final results show the transplanted fat cell integration after 360 days.

[Lower limb repair. Bipedicled fasciocutaneous flap. A new technical approach].

The authors present an anatomical study of a fasciocutaneous flap of the lower limb and its clinical application. Sixteen patients with loss of cutaneous substance and exposure of the leg bone were operated on. The bipedicled fasciocutaneous flap presented by the authors allows the coverage of large areas of the lower limb in the initial stage of treatment.

Cell responses to acoustic stimuli in the pterothoracic ganglion of two noctuoid moths.

The spike activity of various types of cell responses in the pterothoracic ganglion of Ascalapha odorata (Noctuidae) and Empyreuma pugione (Arctiidae) was studied. Pure tones (16 kHz for A. odorata and 20 kHz for E.

Ovarian and feto-placental factors and the regulation of prolactin release during pregnancy in the rat.

Administration of progesterone (5 or 10 mg) to pregnant rats increased serum prolactin significantly on the afternoon of Days 4, 6, 7 and 8 of pregnancy, but had no effect on later days. On Day 10 progesterone administration increased serum prolactin only in rats treated with oestrogen the day before. A similar treatment with oestrogen and progesterone was unable to stimulate secretion on the afternoon of Day 13 of pregnancy.

The distal pedicle fascia flap of the leg.

An anatomical study was undertaken in order to obtain data on the vascularity of the posterior fascia of the leg. Injection studies revealed there to be three "distal" pedicles; one between the peroneal and soleus muscles, emerging 10-15 cm above the lateral malleolus and two other, smaller ones, 5 cm above the medial and lateral malleolus. Clinical experience included seven cases: five with trauma and two with varicose ulcers.

Effect of synthetic thyrotrophin releasing factor on prolactin and luteinizing hormone secretion in male and female rats during various reproductive states.

The effect of synthetic thyrotrophin releasing factor (TRF) on serum prolactin and LH concentrations was determined by radioimmunoassay in male, cyclic and pseudopregnant female rats. A solution of TRF (0-1, 0-25, 0-5 and 1 mug/rat) was injected i.v.
