An epiretinal membrane (ERM) is a product of abnormal cell proliferation on the inner surface of the retina and at the vitreomacular interface. Laser therapy is an interesting modality for treating pathologies of the vitreomacular interface. The wise choice of laser settings (wavelength, exposure time, power) minimizes damage to the retina and ensures a good therapeutic effect. This could be a serious impetus to the development and refinement of laser technologies for treating ERM. This work investigates the biophysical response of structural retinal components, including the dynamics of temperatures and acoustic oscillations, protein denaturation, and stimulation of tissue regeneration, to a quasi-cw laser beam and a subsequent series of laser micropulses. The manuscript also analyzes the mechanisms underlying the therapeutic effect of the proposed laser therapy in patients with ERM.

This text’s main objective is to introduce the assumptions of the Jungian depth psychology to the bibliotherapeutic process. Bibliotherapy as an interdisciplinary method using psychology and literary studies enriched with the theory of integral psychology formulates a new theoretical perspective and constitutes a proposition of holistic view of bibliotherapy. The extension of the theoretical basis of bibliotherapy will help to augment the therapeutic effect, activate the unconscious (the sphere neglected in school education), and strengthen psyche. Integral bibliotherapy shall create conditions to expand the dialogue between the rational side and unconscious one, and it will contribute to a positive stimulation of the integration processes. Providing archetypal patterns reflecting the rules of life in culture, and drawing attention to the regulatory role of literary works, will enrich both the intellectual and spiritual side of the development of the participant of the bibliotherapeutic process. Archetypal content present in literary texts studied by the participant according to the bibliotherapeutic procedure will achieve an integral orientation focused on the humanistic dimension of existence.


Epiretinal membrane (ERM), also known as macular pucker, premacular fibroplasia, premacular gliosis, or cellophane maculopathy is a common vitreoretinal interface pathology that can result in mild to moderate visual impairment with an impact on the quality of life. ERM can be classified as primary “idiopathic” or secondary. Most ERMs occur in individuals older than 50 years, and the prevalence of ERM increases as age increases. The pathological mechanisms are not entirely known, however, the posterior vitreous detachment is thought to be key. Diagnosis and classification of ERM are based on clinical examination findings. However, high resolution spectral domain-optic coherence tomographies (SD-OCTs) have proven to be more sensitive than clinical examination for the diagnosis of numerous disorders of the vitreomacular interface, including ERM. SD-OCTs enable the pre-and postoperative comparison of macular structures in a non-invasive examination. In treatment, surgical intervention entails pars plana vitrectomy with ERM removal with or without internal limiting membrane (ILM) removal. Good visual recovery was present in most patients after surgery.

There were 40 patients with a metabolic syndrome with erectile dysfunction under observation. All patients received physiotherapy exercises, psychotherapeutic correction of a sex disadaptation, epicutaneous electrical stimulation of cavernous bodies of a penis and muscles of a pelvic bottom, and acupuncture according to specially developed scheme. It is proved that the combination of medical methods provides duration of therapeutic effect after course of treat-ment. Normalization of integrated indicators of the International index of erectile function came at 72,5% of patients. Vegetative indicators reached values of norm at 72,5% of patients, normalization of volume of a prostate came at 72,5% of patients, a prostate hemodynamic – at 70% of patients. The penil hemodynamic was normalized at 72,5% of patients. Normalization of functional activity hypothalamic – adrenal and testicular system came at 70% of patients. Components of a copulative cycle reached values of norm at 70% of patients. Carbohydrate metabolism was normalized at 75%, lipide – at 72,5%, biochemical markers of endothelial dysfunction – at 72,5% of patients, the index of exacerbations of a metabolic syndrome decreased by 1,9 times. The remote results of therapeutic effect in 1 year after treatment showed that appreciable improvement was observed at 55%, improvement – at 25%, without improvement – at 20% of patients.

To investigate the effect of Genkwa external application on frostbite model of mices and rats. Used cryostat water immersion method produced frostbite model of mices and rats, objected the Genkwa decoction of high, medium and low doses group and the Genkwa paste of high, low does group to the frostbite Swelling and hemorheology of rats.The Genkwa decoction of high, medium and low doses group and the Genkwa paste of high, low does group topical external application to the frostbite model of mices and rats, made the left posterior reduce paw swelling significantly, reduced legs weight significantly and improved hemorheological indexes significantly. External application Genkwa have a good therapeutic effect to the frostbite model of mices and rats.
