Adhesivo de fibrina intracameral como tratamiento de perforación corneal espontánea / Intracameral fibrin glue in spontaneous corneal perforation

CASO CLÍNICO: Paciente varón de 70 años remitido a nuestro servicio por una perforación corneal en el ojo izquierdo (OI) de posible origen herpético. Se procedió a su reparación mediante la introducción de pegamento tisular de fibrina (Tissucol®) en cámara anterior, colocación de parche de membrana amniótica y lente terapéutica de gran diámetro. En el postoperatorio presentó cierre de la perforación y resolución de la fibrina intracameral sin daño endotelial. DISCUSIÓN: El pegamento tisular de fibrina puede ser utilizado en cámara anterior para tratar perforaciones corneales con excelentes resultados

CASE REPORT: A 70-year-old male was referred to our department due to a herpetic corneal perforation in the left eye. The perforation was healed with intracameral fibrin tissue sealant (Tissucol®), an amniotic membrane, and a large diameter soft contact lens. Postoperatively there were complete dissolution of the fibrin sealant and closure of the perforation without endothelial damage. DISCUSSION: Intracameral fibrin glue may be effective in the closure of corneal perforations

Follicular atresia and LH concentrations during the follicular phase of the estrous cycle in the goat (Capra hircus).

The objective of the study was to identify the effects of LH on the final follicle maturation process as well as the incidence of atresia during the follicular phase of the goat's estrous cycle. In Experiment 1, concentrations of the LH were measured during the follicular phase of a synchronized cycle in 8 Canary goats. In Experiment 2, the same animals were synchronized again. On each day of a 4-day experimental period (day 0 = day of sponges withdrawal), 2 of the goats were bilaterally ovariectomized. Follicles with a diameter > 1 mm were dissected out to obtain qualitative histological data in normal, early atretic I, early atretic II, advanced atretic I and advanced atretic II follicles. The total interval from sponge withdrawal to LH peak was 77.5 +/- 9.8 h. LH peak concentration averaged 44 +/- 5.3 ng/ml and the mean length of the preovulatory surge (amounts over 10 ng/ml) was 8.9 +/- 0.9 h. During the total follicular phase, there were more atretic follicles than normal follicles (58 vs. 30, P < 0.05). The number of early and advanced atretic follicles was similar. There were more early atresia I than early atresia II follicles (23 vs. 6, P < 0.05). On day 2, the number of advanced atretic follicles was greater than early atretic follicles (10 vs. 4, P < 0.05). There was an increase in the number of early atretic follicles from day 2 to day 4 (4 vs. 9, P < 0.05), which was consistent with the effects of the preovulatory LH surge.
