Objective: The purpose of this study was to understand the complex anatomical structure and function of the midbrain to better understand the patient's symptoms and plan effective treatment including pharmacological and rehabilitation interventions. Design: A single case study Methods: A 17-year-old girl presented with acute onset of drowsiness, gait disturbance, mutism, and ptosis. Physical examination revealed postural instability, rigidity of all limbs, and limitations in extraocular movement. The brain MRI revealed an isolated acute infarction in the bilateral midbrain. Considering the location of the infarction, the presenting symptoms were the result of an impairment of the dopaminergic pathway in addition to lesions in the nuclei of the oculomotor nerve. Levodopa/carbidopa was prescribed. And the intensive and comprehensive rehabilitation program was done. Results: As a result of the study, through comprehensive intervention, which encompassed assessments such as the manual muscle test, Korean Modified Barthel Index score, and Trail-making test, significant enhancements in the patient's condition were observed. These findings provide evidence supporting the effectiveness of the intervention in promoting the patient's physical functioning and overall well-being. Conclusions: The results of this case highlight the significance of comprehending the intricate anatomical structure and functional aspects of the midbrain, which led us to approach appropriate pharmacological and rehabilitation interventions. Through active communication among the medical team, we were able to establish a therapeutic plan, which demonstrated that effective treatment can be achieved.

The role of central dopaminergic neural activity for the maintenance of hypertension was tested. Two groups of animals were prepared; 1) Spontaneously hypertensive rats (SHR) at 14 weeks of age which reveal hypertension and 2) age-matched normotensive Wistar Kyoto rats (WKY). Blood pressures and dopamine turnover rate were measured from animals in each group. Dopamine turnover rate was determined in four brain regions such as telence-phalon, hypothalamus/thalamus, midbrain and pons/medulla, from concentration of dopamine at time zero, 1 and 2 hours after alpha-methyl-para-tyrosine (AMPT) was injected into animals. In SHR dopamine turnover rate was greater than normotensive rats in only midbrain. The result from the present study implicates that dopaminergic neural activity in midbrain may be positively coupled to the manifestation of hypertension in SHR.

Midbrain gliomas are relatively rare neoplasms with a generally benign prognosis, with dissemination or metastasis not previously reported. We describe here a woman, in whom magnetic resonance imaging scans showed hydrocephalus and a tegmental lesion in the upper aqueduct. Endoscopic third ventriculostomy and biopsy were performed; during surgery, a second small lesion was observed in the infundibular recess. Histologically, the two lesions had the characteristics of low grade astrocytoma, suggesting that the midbrain astrocytoma may have been disseminated via the cerebral spinal fluid to the infundibular recess. Postoperatively this patient received radiotherapy for nearly one month. Although patients with these tumors are not usually administered adjunctive therapy, radiation and, combined modality therapy, including surgery, radiotherapy, and chemotherapy, may be beneficial in patients with midbrain gliomas with dissemination.

Objectives : The aim of this study is to report the effect of Korean medicine treatment on ocular motility disorders (ptosis, bilateral upward gaze palsy, adduction impairment, and strabismus) caused by thalamus, midbrain and pontine infarctions.Methods : The patient was treated by using acupuncture, hominis placenta pharmacoacupuncture, and electroacupuncture treatment. The change of ptosis was evaluated by measurement of palpebral fissure width. The change of gaze palsy and strabismus were evaluated by comparison the photographs of the extraocular movements of patient. Strabismus also was evaluated by corneal reflex test.Results : Gaze palsy and strabismus were improved. Ptosis disappeared after Korean medicine treatment.Conclusions : Korean medicine treatment should be effective for the ocular motility disorders caused by thalamus, midbrain and pontine infarctions.

The purpose of this case study is to present a case of oculolmotor nerve palsy due to midbrain infarction improved by acupuncture and herb medicine. Oculomotor nerve palsy is a disorder associated with dysfunction in the third cranial nerve, which causes eye movement disorder, diplopia and ptosis. The patient, who was diagnosed with Benedikt's Syndrome(Red Nucleus Syndrome), was given oriental medical treatment. Benetikt's Syndrome has the various symptoms of weakness on one side(contralateral) and eye movement disorder, ptosis, diplopia(ipsilateral) etc., but research on Benetikt's Syndrome or midbrain infarction is scant. Results of this study suggest a role for conservative therapy with herb medicine and acupuncture to treat oculomotor nerve palsy(eye movement disorder, ptosis, diplopia, etc., ipsilateral) and right motor weakness(contralateral) due to midbrain infarction. Further research into oriental medical treatment for such disorders will be forthcoming.

Objectives: This is a case report about the effect of Korean medicine on blepharoptosis and ocular motility disorders that occur with thalamus, midbrain, and cerebellum infarctions. Methods: The patient was treated using Korean medicine such as acupuncture, moxibustion, and herbal medicine (Boyanghwano-tang-gamibang). The change of blepharoptosis was evaluated by measurement of palpebral fissure width (PFW), marginal reflex distance-1 (MRD1), and marginal reflex distance-2 (MRD2). The change inocular motility disorders was evaluated by comparison using photographs of the extraocular movements of the patient. We used the Numeric Rating Scale-11 (NRS-11) of diplopia and dizziness to evaluate the effectiveness of treatment. Results: After treatment, blepharoptosis and ocular motility disorders were improved. The NRS-11 score of dizziness decreased from 10 to 7, and diplopia disappeared after Korean medicine treatment. Conclusions: According to this study, Korean medicine can be effective for treating blepharoptosis and ocular motility disorders in thalamus, midbrain, and cerebellum infarctions.

A 51-year-old man developed diplopia while driving. The brain CT film demonstrated a hemorrhage in the left midbrain and thalamus. On our first diagnosis after 8 days from onset, partial ptosis and limitation of adduction in the left eye were detected. We evaluated that the patinet's digestive system was weak, so that treated the patient with Bojungikki-tang and Sa-am acupuncture Bi-Jung-Geouk(脾正格). As a result, limitation of adduction was recovered to about 90% of normal range and Ptosis was recovered just likely with the normal eye.

Gonadotropin-releasing hormone (GnRH) was originally isolated as a hypothalamic peptide that regulates reproduction by stimulating the release of gonadotropins. Using comparative animal models has led to the discovery that GnRH has a more ancient evolutionary origin. Durinq evolution GnRH peptide underwent gene duplication and structural changes to give rise to multiple molecular forms of GnRHs. Mammalian GnRH initially considered to be the sole molecular form, is now grouped as a family of peptides along with GnRH variants determined from representatives in all classes of vertebrates. Vertebrate species including primates and humanshave more than one GnRH variant in individual brains; a unique GnRH form in the forebrain and chicken IIGnRH in the midbrain. Furthermore, several species of bony fish have three molecular variants of GnRH: salmon GnRH sea-bream GnRH and chicken II GnRH. Also, it has been shown that in addition to the olfactory placodes and the midbrain, there is a third embryonic source of GnRH neurons from the basal diencephalon in birds and fish, which might be true for other vertebrates. Therefore, comparative animal models like fish with discrete sites of expression of three molecular variants of GnRH in individual brains, could provide insight into novel functions of GnRH variants, conservation of gene regulation, and mechanisms governing reproduction in vertebrates.
