Ability of antibody-bound human sperm to penetrate zona-free hamster ova in vitro.

Sera from men and women at risk for immunologic causes of infertility were screened for sperm-specific antibodies by a new test devised to assess directly the presence of immunoglobulins bound to the sperm plasma membrane. Passive antibody transfers to antibody-negative sperm of a fertile donor were performed with the use of sera that possessed iso- or auto-antibodies directed against the sperm head, including the acrosome and postacrosomal regions. The ability of these antibody-bound sperm to penetrate the zona-free hamster egg in vitro, a prerequisite for fertilization, was enhanced, as compared with the penetrating ability of antibody-free sperm of the same donor. These results indicate that the sperm-specific antibodies studied in these experiments, although bound to the sperm head, do not cause infertility by interfering with the acrosome reaction or gamete membrane fusion.

The handling of resistances in adult patients.

In this paper I wish to show in detail clinical material, and how by using this we investigate the semantic distortion, and the use of linguistics as applied to investigating clinical psychoanalysis. In Part IV, I am referring to Freud's patient the "Rat Man'. Compliance with the requirements of the setting, that is, being punctual, associating freely or pretending to, does not mean that many of the patients we are going to discuss here may not put the psychoanalytic setting and language to the service of secret resistances and hidden pregenital pleasure. Perhaps it would be more adequate to say, of a certain type of resistance. But as it happens in the case of my patients illustrated in Parts II and III, we must investigate the meaning of the patients distorted notion of psychoanalytic treatment. This distorted notion we call semantic distortion. Some times it is an apparent formal response which hides another secret level of using the therapist. Sometimes, the apparent formal compliance with the fundamental rule and with the setting, does not prevent the patient from using speech, tenses of verbs, tone of voice, questions, etc. with purposes which are very different from those we know of as adult communication. We are interested in investigating this use of verbal and bodily communications in the service of resistance. In many cases this resistance may be subtle, insidious or hidden, that is to say, more disguised than or different from those described by Freud in some of his first papers as resistance against speaking, evoking memories, associating: all these are easily observable signs which help the therapist to be on the alert. We are interested in exploring the communicational approach, that is, what the messages and speech modalities of the patient are, what they convey and contain.

CT diagnosis of a gastric trichobezoar.

Computed tomography (CT) for the evaluation of a palpable upper abdominal mass was performed in a young woman. The study demonstrated a non-attached intragastric mass which contained small amounts of air. Gastric bezoar was confidently diagnosed based on these findings.

Psychoanalysis of the impulsive character: a linguistic-communicative study.

The importance of the mode of communication, the dreams, and the linguistic study of impulsive patients is examined. The significance of the use of the imperative mood, with a rapid evacuation rhythm and good synchronization between the verbal and paraverbal levels is explicated. The obvious linguistic differences between sessions show, together with thematic clues, that it would be possible to predict impulsive discharges, that is, to formulate a predictive theory. The concept is defined, and clinical material is provided to illustrate the concept. A linguistic analysis of the patient's dreams is presented, as well as a thematic approach to the dreams. The ultilization of linguistics in psychoanalysis is systematized, and the verbs used by the patient are listed.
